delivered the opinion of the Court.
Zoning ordinances adopted by the city of Detroit differentiate between motion picture theaters which exhibit sexually explicit “adult” movies and those which do not. The principal question presented by this case is whether that statutory classification is unconstitutional because it is based on the content of communication protected by the First Amendment.1
Effective November 2, 1972, Detroit adopted the ordinances challenged in this litigation. Instead of concentrating “adult” theaters in limited zones, these ordinances require that such theaters be dispersed. Specifically, an adult theater may not be located within 1,000 feet of any two other “regulated uses” or within 500 feet of a residential area.2 The term “regulated uses” includes 10 different kinds of establishments in addition to adult theaters.3
[53]*53The classification of a theater as “adult” is expressly predicated on the character of the motion pictures which it exhibits. If the theater is used to present “material distinguished or characterized by an emphasis on matter depicting, describing or relating to 'Specified Sexual Activities’ or 'Specified Anatomical Areas,’ ” 4 it is an adult establishment.5
[54]*54The 1972 ordinances were amendments to an “Anti-Skid Row Ordinance” which had been adopted 10 years earlier. At that time the Detroit Common Council made a finding that some uses of property are especially injurious to a neighborhood when they are concentrated in limited areas.6 The decision to add adult motion picture theaters and adult book stores to the list of businesses which, apart from a special waiver,7 could not be located within 1,000 feet of two other “regulated uses,” was, in part, a response to the significant growth in the number [55]*55of such establishments.8 In the opinion of urban planners and real estate experts who supported the ordinances, the location of several such businesses in the same neighborhood tends to attract an undesirable quantity and quality of transients, adversely affects property values, causes an increase in crime, especially prostitution, and encourages residents and businesses to move elsewhere.
Respondents are the operators of two adult motion picture theaters. One, the Nortown, was an established theater which began to exhibit adult films in March 1973. The other, the Pussy Cat, was a corner gas station which was converted into a “mini theater,” but denied a certificate of occupancy because of its plan to exhibit adult films. Both theaters were located within 1,000 feet of two other regulated uses and the Pussy Cat was less than 500 feet from a residential area. The respondents brought two separate actions against appropriate city officials, seeking a declaratory judgment that the ordinances were unconstitutional and an injunction against their enforcement. Federal jurisdiction was properly invoked9 and the two cases were consolidated for decision.10
The District Court granted defendants’ motion for summary judgment. On the basis of the reasons stated [56]*56by the city for adopting the ordinances, the court concluded that they represented a rational attempt to preserve the city’s neighborhoods.11 The court analyzed and rejected respondents’ argument that the definition and waiver provisions in the ordinances were impermis-sibly vague; it held that the disparate treatment of adult theaters and other theaters was justified by a compelling state interest and therefore did not violate the Equal Protection Clause;12 and finally it concluded that the regulation of the places where adult films could be shown did not violate the First Amendment.13
[57]*57The Court of Appeals reversed. American Mini Theatres, Inc. v. Gribbs, 518 F. 2d 1014 (CA6 1975). The majority opinion concluded that the ordinances imposed a prior restraint on constitutionally protected communication and therefore “merely establishing that they were designed to serve a compelling public interest” provided an insufficient justification for a classification of motion picture theaters on the basis of the content of the materials they purvey to the public.14 Relying primarily on Police Department of Chicago v. Mosley, 408 U. S. 92, the court held the ordinance invalid under the Equal Protection Clause. Judge Celebrezze, in dissent, ex[58]*58pressed the opinion that the ordinance was a valid “ 'time, place and manner’ regulation,” rather than a regulation of speech on the basis of its content.15
Because of the importance of the decision, we granted certiorari, 423 U. S. 911.
As they did in the District Court, respondents contend (1) that the ordinances are so vague that they violate the Due Process Clause of the Fourteenth Amendment; (2) that they are invalid under the First Amendment as prior restraints on protected communication; and (3) that the classification of theaters on the basis of the content of their exhibitions violates the Equal Protection Clause of the Fourteenth Amendment. We consider their arguments in that order.

There are two parts to respondents’ claim that the ordinances are too vague. They do not attack the specificity of the definition of “Specified Sexual Activities” or “Specified Anatomical Areas.” They argue, however, that they cannot determine how much of the described activity may be permissible before the exhibition is “characterized by an emphasis” on such matter. In addition, they argue that the ordinances are vague because they do not specify adequate procedures or standards for obtaining a waiver of the 1,000-foot restriction.
We find it unnecessary to consider the validity of either of these arguments in the abstract. For even if there may be some uncertainty about the effect of the [59]*59ordinances on other litigants, they are unquestionably applicable to these respondents. The record indicates that both theaters propose to offer adult fare on a regular basis.16 Neither respondent has alleged any basis for claiming or anticipating any waiver of the restriction as applied to its theater. It is clear, therefore, that any element of vagueness in these ordinances has not affected these respondents. To the extent that their challenge is predicated on inadequate notice resulting in a denial of procedural due process under the Fourteenth Amendment, it must be rejected. Cf. Parker v. Levy, 417 U. S. 733, 754-757.
Because the ordinances affect communication protected by the First Amendment, respondents argue that they may raise the vagueness issue even though there is no uncertainty about the impact of the ordinances on their own rights. On several occasions we have determined that a defendant whose own speech was unprotected had standing to challenge the constitutionality of a statute which purported to prohibit protected speech, or even speech arguably protected.17 This ex[60]

S. 733, 754-757.
Because the ordinances affect communication protected by the First Amendment, respondents argue that they may raise the vagueness issue even though there is no uncertainty about the impact of the ordinances on their own rights. On several occasions we have determined that a defendant whose own speech was unprotected had standing to challenge the constitutionality of a statute which purported to prohibit protected speech, or even speech arguably protected.17 This ex[60]*60ception from traditional rules of standing to raise constitutional issues has reflected the Court’s judgment that the very existence of some statutes may cause persons not before the Court to refrain from engaging in constitutionally protected speech or expression. See Broadrick v. Oklahoma, 413 U. S. 601, 611-614. The exception is justified by the overriding importance of maintaining a free and open market for the interchange of ideas. Nevertheless, if the statute’s deterrent effect on legitimate expression is not “both real and substantial,” and if the statute is “readily subject to a narrowing construction by the state courts,” see Erznoznik v. City of Jacksonville, 422 U. S. 205, 216, the litigant is not permitted to assert the rights of third parties.
We are not persuaded that the Detroit zoning ordinances will have a significant deterrent effect on the exhibition of films protected by the First Amendment. [61]*61As already noted, the only vagueness in the ordinances relates to the amount of sexually explicit activity that may be portrayed before the material can be said to be “characterized by an emphasis” on such matter. For most films the question will be readily answerable; to the extent that an area of doubt exists, we see no reason why the ordinances are not “readily subject to a narrowing construction by the state courts.” Since there is surely a less vital interest in the uninhibited exhibition of material that is on the borderline between pornography and artistic expression than in the free dissemination of ideas of social and political significance, and since the limited amount of uncertainty in the ordinances is easily susceptible of a narrowing construction, we think this is an inappropriate case in which to adjudicate the hypothetical claims of persons not before the Court.
The only area of protected communication that may be deterred by these ordinances comprises films containing material falling within the specific definitions of “Specified Sexual Activities” or “Specified Anatomical Areas.” The fact that the First Amendment protects some, though not necessarily all, of that material from total suppression does not warrant the further conclusion that an exhibitor’s doubts as to whether a borderline film may be shown in his theater, as well as in theaters licensed for adult presentations, involves the kind of threat to the free market in ideas and expression that justifies the exceptional approach to constitutional adjudication recognized in cases like Dombrowski v. Pfister, 380 U. S. 479.
The application of the ordinances to respondents is plain; even if there is some area of uncertainty about their application in other situations, we agree with the District Court that respondents’ due process argument must be rejected.
[62]*62II
Petitioners acknowledge that the ordinances prohibit theaters which are not licensed as “adult motion picture theaters” from exhibiting films which are protected by the First Amendment. Respondents argue that the ordinances are therefore invalid as prior restraints on free speech.
The ordinances are not challenged on the ground that they impose a limit on the total number of adult theaters which may operate in the city of Detroit. There is no claim that distributors or exhibitors of adult films are denied access to the market or, conversely, that the viewing public is unable to satisfy its appetite for sexually explicit fare. Viewed as an entity, the market for this commodity is essentially unrestrained.
It is true, however, that adult films may only be exhibited commercially in licensed theaters. But that is also true of all motion pictures. The city's general zoning laws require all motion picture theaters to satisfy certain locational as well as other requirements; we have no doubt that the municipality may control the location of theaters as well as the location of other commercial establishments, either by confining them to certain specified commercial zones or by requiring that they be dispersed throughout the city. The mere fact that the commercial exploitation of material protected by the First Amendment is subject to zoning and other licensing requirements is not a sufficient reason for invalidating these ordinances.
Putting to one side for the moment the fact that adult motion picture theaters must satisfy a locational restriction not applicable to other theaters, we are also persuaded that the 1,000-foot restriction does not, in itself, create an impermissible restraint on protected communication. The city's interest in planning and regulating the use of property for commercial purposes [63]*63is clearly adequate to support that kind of restriction applicable to all theaters within the city limits. In short, apart from the fact that the ordinances treat adult theaters differently from other theaters and. the fact that the classification is predicated on the content of material shown in the respective theaters, the regulation of the place where such films may be exhibited does not offend the First Amendment.18 We turn, therefore, to the question whether the classification is consistent with the Equal Protection Clause.

A remark attributed to Voltaire characterizes our zealous adherence to the principle that the government may not tell the citizen what he may or may not say. Referring to a suggestion that the violent overthrow of tyranny might be legitimate, he said: “I disapprove of what you say, but I will defend to the death your right to say it.” 19 The essence of that comment has been repeated time after time in our decisions invalidating attempts by the government to impose selective controls upon the dissemination of ideas.
Thus, the use of streets and parks for the free expression of views on national affairs may not be conditioned upon the sovereign's agreement with what a speaker may intend to say.20 Nor may speech be curtailed because it [64]*64invites dispute, creates dissatisfaction with conditions the way they are, or even stirs people to anger.21 The sovereign's agreement or disagreement with the content of what a speaker has to say may not affect the regulation of the time, place, or manner of presenting the speech.
If picketing in the vicinity of a school is to be allowed to express the point of view of labor, that means of expression in that place must be allowed for other points of view as well. As we said in Mosley:
“The central problem with Chicago’s ordinance is that it describes permissible picketing in terms of its subject matter. Peaceful picketing on the subject of a school’s labor-management dispute is permitted, but all other peaceful picketing is prohibited. The operative distinction is the message on a picket sign. But, above all else, the First Amendment means that government has no power to restrict expression because of its message, its ideas, its subject matter, or its content. Cohen v. California, 403 U. S. 15, 24 (1971); Street v. New York, 394 U. S. 576 (1969); New York Times Co. v. Sullivan, 376 U. S. 254, 269-270 (1964), and cases cited; NAACP v. Button, 371 U. S. 415, 445 (1963); Wood v. Georgia, 370 U. S. 375, 388-389 (1962); Terminiello v. Chicago, 337 U. S. 1, 4 (1949); De Jonge v. Oregon, 299 U. S. 353, 365 (1937). To permit the continued building of our politics and culture, and to assure self-fulfillment for each individual, our people are guaranteed the right to express any thought, free from government censorship. The essence of this forbidden censorship is content control. Any restriction on expressive activity because of its con[65]*65tent would completely undercut the ‘profound national commitment to the principle that debate on public issues should be uninhibited, robust, and wide-open.' New York Times Co. v. Sullivan, supra, at 270.
“Necessarily, then, under the Equal Protection Clause, not to mention the First Amendment itself, government may not grant the use of a forum to people whose views it finds acceptable, but deny use to those wishing to express less favored or more controversial views. And it may not select which issues are worth discussing or debating in public facilities. There is an ‘equality of status in the field of ideas,’ and government must afford all points of view an equal opportunity to be heard. Once a forum is opened up to assembly or speaking by some groups, government may not prohibit others from assembling or speaking on the basis of what they intend to say. Selective exclusions from a public forum may not be based on content alone, and may not be justified by reference to content alone.” 408 U. S., at 95-96. (Footnote omitted.)
This statement, and others to the same effect, read literally and without regard for the facts of the case in which it was made, would absolutely preclude any regulation of expressive activity predicated in whole or in part on the content of the communication. But we learned long ago that broad statements of principle, no matter how correct in the context in which they are made, are sometimes qualified by contrary decisions before the absolute limit of the stated principle is reached.22 When we review this Court's actual adjudications in the First Amendment area, we find this to have been the case [66]*66with the stated principle that there may be no restriction whatever on expressive activity because of its content.
The question whether speech is, or is not, protected by the First Amendment often depends on the content of the speech. Thus, the line between permissible advocacy and impermissible incitation to crime or violence depends, not merely on the setting in which the speech occurs, but also on exactly what the speaker had to say.23 Similarly, it is the content of the utterance that determines whether it is a protected epithet or an unprotected “fighting comment.” 24 And in time of war “the publication of the sailing dates of transports or the number and location of troops” may unquestionably be restrained, see Near v. Minnesota ex rel. Olson, 283 U. S. 697, 716, although publication of news stories with a different content would be protected.
Even within the area of protected speech, a difference in content may require a different governmental response. In New York Times Co. v. Sullivan, 376 U. S. 264, we recognized that the First Amendment places limitations on the States’ power to enforce their libel laws. We held that a public official may not recover damages from a critic of his official conduct without proof of “malice” as specially defined in that opinion.25 Implicit in the opinion is the assumption that if the content of the newspaper article had been different — that is, if its subject matter had not been a public official — a lesser standard of proof would have been adequate.
[67]*67In a series of later cases, in which separate individual views were frequently stated, the Court addressed the broad problem of when the New York Times standard of malice was required by the First Amendment. Despite diversity of opinion on whether it was required only in cases involving public figures, or also in cases involving public issues, and on whether the character of the damages claim mattered, a common thread which ran through all the opinions was the assumption that the rule to be applied depended on the content of the communication.26 But that assumption did not contradict the underlying reason for the rule which is generally described as a prohibition of regulation based on the content of protected communication. The essence of that rule is the need for absolute neutrality by the government; its regulation of communication may not be affected by sympathy or hostility for the point of view being expressed by the communicator.27 Thus, although [68]*68the content of a story must be examined to decide whether it involves a public figure or a public issue, the Court’s application of the relevant rule may not depend on its favorable or unfavorable appraisal of that figure or that issue.
We have recently held that the First Amendment affords some protection to commercial speech.28 We have also made it clear, however, that the content of a particular advertisement may determine the extent of its protection. A public rapid transit system may accept some advertisements and reject others.29 A state statute may permit highway billboards to advertise businesses located in the neighborhood but not elsewhere,30 and regulatory commissions may prohibit businessmen from making statements which, though literally true, are potentially deceptive.31 The measure of constitutional pro[69]*69tection to be afforded commercial speech will surely be governed largely by the content of the communication.32
More directly in point are opinions dealing with the question whether the First Amendment prohibits the State and Federal Governments from wholly suppressing sexually oriented materials on the basis of their “obscene character.” In Ginsberg v. New York, 390 U. S. 629, the Court upheld a conviction for selling to a minor magazines which were concededly not “obscene” if shown to adults. Indeed, the Members of the Court who would accord the greatest protection to such materials have repeatedly indicated that the State could prohibit the distribution or exhibition of such materials to juveniles and unconsenting adults.33 Surely the First Amendment does [70]*70not foreclose such a prohibition; yet it is equally clear that any such prohibition must rest squarely on an appraisal of the content of material otherwise within a constitutionally protected area.
Such a line may be drawn on the basis of content without violating the government's paramount obligation of neutrality in its regulation of protected communication. For the regulation of the places where sexually explicit films may be exhibited is unaffected by whatever social, political, or philosophical message a film may be intended to communicate; whether a motion picture ridicules or characterizes one point of view or another, the effect of the ordinances is exactly the same.
Moreover, even though we recognize that the First Amendment will not tolerate the total suppression of erotic materials that have some arguably artistic value, it is manifest that society's interest in protecting this type of expression is of a wholly different, and lesser, magnitude than the interest in untrammeled political debate that inspired Voltaire's immortal comment. Whether political oratory or philosophical discussion moves us to applaud or to despise what is said, every schoolchild can understand why our duty to defend the right to speak remains the same. But few of us would march our sons and daughters off to war to preserve the citizen’s right to see “Specified Sexual Activities” exhibited in the theaters of our choice. Even though the First Amendment protects communication in this area from total suppression, we hold that the State may legitimately use the content of these materials as the basis [71]*71for placing them in a different classification from other motion pictures.
The remaining question is whether the line drawn by these ordinances is justified by the city’s interest in preserving the character of its neighborhoods. On this question we agree with the views expressed by District Judges Kennedy and Gubow. The record discloses a factual basis for the Common Council’s conclusion that this kind of restriction will have the desired effect.34 It is not our function to appraise the wisdom of its decision to require adult theaters to be separated rather than concentrated in the same areas. In either event, the city’s interest in attempting to preserve the quality of urban life is one that must be accorded high respect. Moreover, the city must be allowed a reasonable opportunity to experiment with solutions to admittedly serious problems.
Since what is ultimately at stake is nothing more than a limitation on the place where adult films may be exhibited,35 even though the determination of whether a [72]*72particular film fits that characterization turns on the nature of its content, we conclude that the city's interest in the present and future character of its neighborhoods adequately supports its classification of motion pictures. We hold that the zoning ordinances requiring that adult [73]*73motion picture theaters not be located within 1,000 feet of two other regulated uses does not violate the Equal Protection Clause of the Fourteenth Amendment.
