TROTT, Circuit Judge:
I
A.
On June 21, 1988, Daniel Eugene Frazer was charged in a superseding indictment with fifteen counts of bank robbery in violation of 18 U.S.C. § 2113(a). Because he was indigent, an attorney was appointed to represent him.
On advice of appointed counsel, Mr. Frazer waived his right to a trial by jury, and the case was tried to the court on stipulated facts. He was convicted of eight counts and sentenced to a twenty-year term of imprisonment.
Mr. Frazer filed, but later abandoned, an appeal. Subsequently, and for substantial assistance to the Government, his sentence was reduced to fifteen years under Federal Rule of Criminal Procedure 35.
B.
On May 2, 1991, Mr. Frazer filed a pro se motion pursuant to 28 U.S.C. § 2255 to vacate, set aside, or correct his sentence. He alleged inter alia that his appointed trial attorney had failed to provide for him the assistance to which he was entitled under the Sixth Amendment. Specifically, Mr. Frazer claimed in his motion that his appointed trial attorney had called him a “stupid nigger son of a bitch and said he hopes I get life. And if I continue to insist on going to trial I will find him to be very ineffective.” Moreover, Mr. Frazer claimed that two deputy United States Marshals overheard his attorney’s alleged outburst and advised him to get a new lawyer. Mr. Frazer alleges he tried to do so within the hour, but waá rebuffed by the district court. Mr. Frazer also alleged that his appointed trial attorney refused to collect information that would have been helpful in mitigating his sentence.
Mr. Frazer’s Sixth Amendment legal argument, tendered in his Response to the Government’s Opposition to his § 2255 motion, was as follows: ‘When counsel refers/calls its client ‘a stupid nigger son of a bitch’ and promisses [sic] to be ineffective if Petitioner continues to insist upon going to trial rather than plead as counsel insisted a serious conflict exist [sic].” As authority for his argument, he invoked the duty of loyalty owed by an attorney to his client and cited Cuyler v. Sullivan, 446 U.S. 335, 100 S.Ct. 1708, 64 L.Ed.2d 333 (1980), and Strickland v. Washington, 466 U.S. 668, 104 S.Ct. 2052, 80 L.Ed.2d 674 (1984).
C.
Mr. Frazer’s pro se request for relief was denied by the district court on the basis of a recommendation from a magistrate judge. Without holding an evidentiary hearing, the magistrate judge had rejected Mr. Frazer’s allegations of a fatal defect in the manner in which he had been treated by his appointed trial attorney. The magistrate judge dismissed Mr. Frazer’s claims of racial bias as “eonclusory allegations ... unsupported by any facts.” The magistrate judge also believed the record demonstrated that trial counsel’s actual representation of Mr. Frazer did not demonstrate “any errors in preparing for trial or in presenting a defense,” i.e., no prejudice. Thus, no evidentiary hearing was deemed necessary.
Now represented by different counsel, Mr. Frazer appeals. His primary allegation is that the district court abused its discretion in failing to hold an evidentiary hearing on [781]*781whether his Sixth Amendment right to counsel at trial was violated.1
D.
We review de novo both the denial of a § 2255 motion and a determination that the prisoner was not denied his Sixth Amendment right to counsel. United States v. Moore, 921 F.2d 207, 209 (9th Cir.1990); United States v. Birtle, 792 F.2d 846, 847 (9th Cir.1986). The prisoner is entitled to an evidentiary hearing on his claim “[ujnless the motion and the files and records of the case conclusively show that the prisoner is entitled to no relief.” 28 U.S.C. § 2255 (1988). We review for an abuse of discretion the district court’s failure to hold an evidentiary hearing under § 2255, but “[w]hen a defendant’s allegations ... are based on facts outside of the record, an evidentiary hearing is required.” Doganiere v. United States, 914 F.2d 165, 168 (9th Cir.1990) (citing United States v. Espinoza, 866 F.2d 1067, 1069 (9th Cir.1988)), cert. denied, 499 U.S. 940, 111 S.Ct. 1398, 113 L.Ed.2d 454 (1991). An exception to this mandatory requirement exists when the issue of the prisoner’s credibility can be “ ‘conclusively decided on the basis of documentary testimony and evidence in the record.’ ” Espinoza, 866 F.2d at 1069 (quoting Watts v. United States, 841 F.2d 275, 277 (9th Cir.1988)); see also Blackledge v. Allison, 431 U.S. 63, 75-76, 97 S.Ct. 1621, 1630, 52 L.Ed.2d 136 (1977) (vague or palpably incredible or frivolous allegations warrant summary dismissal of a petition for habeas corpus). We have jurisdiction over this timely appeal under 28 U.S.C. § 2255, and we reverse.
II
The government forthrightly conceded at oral argument that in measuring for an abuse of discretion the district court’s decision not to conduct an evidentiary hearing on Mr. Frazer’s Sixth Amendment claim, we must accept arguendo Mr. Frazer’s allegations against his appointed trial attorney as true. We then ask whether these allegations, if proved, would entitle him to the relief he seeks. See United States v. Hearst, 638 F.2d 1190, 1194 (9th Cir.1980), cert. denied, 451 U.S. 938, 101 S.Ct. 2018, 68 L.Ed.2d 325 (1981). We emphasize that no finding has yet been made supporting Mr. Frazer’s claims. Our duty is to decide only whether he must be given an opportunity in the form of an evidentiary hearing to attempt to prove his allegations.
The Sixth Amendment provides: “In all criminal prosecutions, the accused shall enjoy the right ... to have the Assistance of Counsel for his defence.” U.S. ConstAmend. VI. This right has come to be regarded as a sine qua non of our criminal justice system. In 1938, the Supreme Court said:
[T]he Assistance of Counsel ... is one of the safeguards of the Sixth Amendment deemed necessary to insure fundamental human rights of life and liberty.... The Sixth Amendment stands as a constant admonition that if the constitutional safeguards it provides be lost, justice will not “still be done.”
Johnson v. Zerbst, 304 U.S. 458, 462, 58 S.Ct. 1019, 1022, 82 L.Ed. 1461 (1938).
Six years earlier, Justice Sutherland had described the importance of this right as follows:
Even the intelligent and educated layman has small and sometimes no skill in the science of law. If charged with crime, he is incapable, generally, of determining for himself whether the indictment is good or bad.... He requires the guiding hand of counsel at every step of the proceedings against him.
Powell v. Alabama, 287 U.S. 45, 69, 53 S.Ct. 55, 64, 77 L.Ed. 158 (1932) (emphasis added).
For these reasons, the Court held in Johnson v. Zerbst that in federal courts, counsel must be provided free of charge for defen[782]*782dants unable to employ counsel on their own, unless this right is competently and intelligently waived. The Court said, “Since the Sixth Amendment constitutionally entitles one charged with crime to the assistance of counsel, compliance with this constitutional mandate is an essential jurisdictional prerequisite to a federal court’s authority to deprive an accused of his life or liberty.” Johnson v. Zerbst, 304 U.S. at 467, 58 S.Ct. at 1024 (emphasis added). Moreover, the Court has assigned a “special value” to this right: ‘“Of all the rights that an accused person has, the right to be represented by counsel is by far the most pervasive for it affects his ability to assert any other rights he may have.’ ” United States v. Cronic, 466 U.S. 648, 654, 104 S.Ct. 2039, 2044, 80 L.Ed.2d 657 (1984) (quoting Schaefer, Federalism and State Criminal Procedure, 70 Harv.L.Rev. 1, 8 (1956)). Justice Black has described the right to counsel as invested with a “peculiar saeredness.” Avery v. Alabama, 308 U.S. 444, 447, 60 S.Ct. 321, 322, 84 L.Ed. 377 (1940). In this vein, the Court has held that the deprivation of the right to counsel is so inconsistent with the right to a fair trial that it can never be treated as harmless error. Chapman v. California, 386 U.S. 18, 23 n. 8, 87 S.Ct. 824, 828 n. 8, 17 L.Ed.2d 705 (1967) (citing Gideon v. Wainwright, 372 U.S. 335, 83 S.Ct. 792, 9 L.Ed.2d 799 (1963)).
The right to counsel guaranteed by the Constitution, however, means more than just the opportunity to be physically accompanied by a person privileged to practice law. See Strickland v. Washington, 466 U.S. 668, 685, 104 S.Ct. 2052, 2063, 80 L.Ed.2d 674 (1984) (“That a person who happens to be a lawyer is present at the trial alongside the accused ... is not enough to satisfy the constitutional command.”); Powell v. Alabama, 287 U.S. at 58, 53 S.Ct. at 60 (indigent defendants provided with unprepared and pro forma lawyers “were not accorded the right to counsel in any substantial sense”). Thus, “[a]n accused is entitled to be assisted by an attorney, whether retained or appointed, who plays the role necessary to ensure that the trial is fair.” Strickland, 466 U.S. at 685, 104 S.Ct. at 2063. In other words, the assistance to which a defendant is entitled must be “effective,” id. at 686, 104 S.Ct. at 2064, unhindered either by the state or by counsel’s Constitutionally deficient performance. This required performance contemplates open communication unencumbered by unnecessary impediments to the exchange of information and advice. See Javor v. United States, 724 F.2d 831, 834 (9th Cir.1984) (a defendant’s Sixth Amendment right to counsel is denied when his attorney sleeps through a substantial portion of the trial); see also Tucker v. Day, 969 F.2d 155, 159 (5th Cir.1992) (an attorney who provided his client with no assistance at sentencing and who said, “Oh, I am just standing in for this one,” did not satisfactorily discharge his Sixth Amendment responsibilities).
Appointed counsel also owes the client a duty of loyalty. This “duty of loyalty” has been described as “perhaps the most basic of counsel’s duties.” Strickland, 466 U.S. at 692, 104 S.Ct. at 2067. As such, this duty prohibits a defense attorney from telling a jury that “it is his view of the evidence that there is no reasonable doubt regarding the only factual issues that are in dispute.” United States v. Swanson, 943 F.2d 1070, 1074 (9th Cir.1991). In Swanson, we held that a defense attorney who so advises a jury “has utterly failed to ‘subject the prosecution’s case to meaningful adversarial testing.’ ” Id. (quoting United States v. Cronic, 466 U.S. 648, 659, 104 S.Ct. 2039, 2047, 80 L.Ed.2d 657 (1984)). In so holding, we cited with approval the Tenth Circuit’s holding that “ ‘an attorney who adopts and acts upon a belief that his client should be convicted “fail[s] to function in any meaningful sense as the Government’s adversary.”’” Id. (quoting Osborn v. Shillinger, 861 F.2d 612, 625 (10th Cir.1988) (quoting Cronic, 466 U.S. at 666, 104 S.Ct. at 2051)).
We have also joined the Tenth Circuit in holding that an attorney who abandons his duty of loyalty to his client may by so doing create a conflict of interest:
A defense attorney who abandons his duty of loyalty to his client and effectively joins the state in an effort to attain a conviction or death sentence suffers from an obvious conflict of interest. Such an attorney, like [783]*783unwanted counsel, “ ‘represents’ the defendant only through a tenuous and unacceptable legal fiction.” Faretta v. California, 422 U.S. 806, 821 [95 S.Ct. 2525, 2534, 45 L.Ed.2d 562] (1975). In fact, an attorney who is burdened by a conflict between his client’s interests and his own sympathies to the prosecution’s position is consider-, ably worse than an attorney with loyalty to other defendants, because the interests of the state and the defendant are necessarily in opposition.
Id. at 1075 (quoting Osborn, 861 F.2d at 629); see also Cuyler v. Sullivan, 446 U.S. 335, 349-50, 100 S.Ct. 1708, 1718-19, 64 L.Ed.2d 333 (1980) (“[A] defendant who shows that a conflict of interest actually affected the adequacy of his representation need not demonstrate prejudice in order to obtain relief.”); Holloway v. Arkansas, 435 U.S. 475, 490-91, 98 S.Ct. 1173, 1181-82, 55 L.Ed.2d 426 (1978).
Nevertheless, the Supreme Court in fleshing out the contours of the Sixth Amendment right to counsel has held that it does not guarantee “a right to counsel with whom the accused has a ‘meaningful attorney-client relationship.’” Morris v. Slappy, 461 U.S. 1, 3-4, 103 S.Ct. 1610, 1612-13, 75 L.Ed.2d 610 (1983); see id. at 13-14, 103 S.Ct. at 1617-18. To understand the dimensions of this limitation, one must look at the facts of that case.2
In Morris, an indigent defendant had a unilateral falling out with his attorney caused not by any identifiable objective misconduct by the attorney, but by (1) Morris’s dissatisfaction with a switch from one public defender to another, (2) Morris’s opinion that the new public defender had not had enough time to prepare for trial, and (3) by the second public defender’s assessment that Morris had no “defense to [the] charges.” See 461 U.S. at 8, 103 S.Ct. at 1614. Because of this unilateral falling out, Morris refused to participate in his own defense. In affirming the denial by the district court of Morris’s petition for a writ of habeas corpus, the Court rejected Morris’s claim that a defendant has the right to a certain “rapport” with his attorney. Id.; see United States v. Schaff, 948 F.2d 501, 505 (9th Cir.1991).
Moreover, an indigent defendant does not have the right to “ ‘an attorney he cannot afford.’ ” Caplin & Drysdale v. United States, 491 U.S. 617, 624, 109 S.Ct. 2646, 2651, 105 L.Ed.2d 528 (1989) (quoting Wheat v. United States, 486 U.S. 153, 159, 108 S.Ct. 1692, 1697, 100 L.Ed.2d 140 (1988)).
Ill
If the Sixth Amendment itself protects an accused from a lawyer with a traditional conflict of interest, and from a lawyer who is asleep, completely disinterested, or so unprepared that his appearance is merely pro forma, surely it must protect the indigent from an appointed lawyer who calls him to his face a “stupid nigger 'son of a bitch” and who threatens to provide substandard performance for him if he chooses to exercise his right to go to trial. An indigent defendant may not be entitled to a meaningful relationship as described in Moms, but a verbal assault manifesting explicit racial prejudice and threatening to compromise the client’s rights far exceeds and transcends the facts and holding in that case. In our judgment, such a verbal assault is irreconcilable with (1) the duty of loyalty owed a client by his attorney, (2) the responsibility of providing meaningful assistance, and (3) the role of “guiding hand” described in Powell by Justice Sutherland.- All advice, assistance, and guidance provided after such an outburst would be fatally suspect, as would the “willingness” of a defendant to follow the attorney’s lead. Such a disrespectful and inappropriate eruption would signal and be tantamount to (unless somehow cured) a “total lack of communication” far exceeding the parameters of any duty on the part of counsel to deliver to his client a “pessimistic prognosis” of his legal position. United [784]*784States v. Rogers, 769 F.2d 1418, 1424 (9th Cir.1985); see also United States v. Walker, 915 F.2d 480, 485 (9th Cir.1990) (a total lack of communication results in ineffective assistance of counsel). Compare Schaff, 948 F.2d at 504-05 (vigorous advocacy by counsel of a plea bargain does not necessarily result in a total lack of communication).
To hold otherwise in this case would reduce a sacred right to worse than a sham. It would be astonishing to hold that the Sixth Amendment right to appointed counsel is satisfied by the provision of an attorney who explicitly assaults his client with racial slurs and makes threatening and improper statements to the client capable of overriding the client’s own judgment as to how he should exercise his various rights. What stands out in this case in contrast to Morris is counsel’s alleged abhorrent, confrontational behavior, including his alleged threat to Mr. Frazer to deny him the assistance to which he was entitled. No such behavior was present in Morris. In that case, Morris had no cognizable or legitimate reason to refuse to cooperate with his counsel or to participate in the trial.
Our conclusion is compelled by the collective teachings of Powell, Johnson, Gideon, and particularly by Justice Black’s description in Von Moltke v. Gillies of appointed counsel’s unique role:
The right to counsel guaranteed by the Constitution contemplates the services of an attorney devoted solely to the interests of his client.... Undivided allegiance and faithful, devoted service to a client are prized traditions of the American lawyer. It is this kind of service for which the Sixth Amendment makes provision. And nowhere is this service deemed more honorable than in case of appointment to represent an accused too poor to hire a lawyer, even though the accused may be a member of an unpopular or hated group, or may be charged with an offense which is peculiarly abhorrent.
332 U.S. 708, 725-26, 68 S.Ct. 316, 324, 92 L.Ed. 309 (1948) (plurality) (footnote omitted).
We will not tolerate the deliberate exclusion of blacks from grand juries because discrimination on the basis of race in the selection of grand jurors “strikes at the fundamental values of our judicial system and our society as a whole.” Rose v. Mitchell, 443 U.S. 545, 556, 99 S.Ct. 2993, 3000, 61 L.Ed.2d 739 (1979). Nor will we permit counsel to use a peremptory challenge to strike a black juror because of that juror’s race. Batson v. Kentucky, 476 U.S. 79, 97, 106 S.Ct. 1712, 1723, 90 L.Ed.2d 69 (1986). “Discrimination within the judicial system is most pernicious because it is ‘a stimulant to that race prejudice which is an impediment to securing to [black citizens] that equal justice which the law aims to secure to all others.’” Id. at 87-88, 106 S.Ct. at 1718 (quoting Strauder v. West Virginia, 100 U.S. 303, 308, 25 L.Ed. 664 (1880)). To countenance the type of overt racially charged threat alleged in this case would be to deviate from our national goal of ending racism.
Accordingly, we hold that the facts as alleged in this case, if proved, would render so defective the relationship inherent in the right to trial counsel guaranteed by the Sixth Amendment that Mr. Frazer would be entitled to a new trial with a different attorney. It follows as night the day that he has demonstrated a right to an evidentiary hearing on this issue, and that the denial of such a hearing in the district court constituted an abuse of discretion. The magistrate’s statement that Mr. Frazer’s allegations are “conclusory” and “unsupported by any facts” is manifestly erroneous, as is the government’s argument in its brief that Mr. Frazer’s claims are “mere folderol.” Moreover, as we have pointed out, Mr. Frazer claimed he had two government witnesses who corroborate his claims. Because all of these factual allegations were outside the record, this claim on its face should have signalled the need for an evidentiary hearing.
Our conclusion is informed by our duty as judges to ensure that the right to counsel, as a jurisdictional prerequisite to depriving a person of his or her liberty, is fully honored. As stated by Justice Black, “where denial of the constitutional right to assistance of counsel is asserted, its peculiar sacredness demands that we scrupulously review the rec[785]*785ord.” Avery v. Alabama, 308 U.S. 444, 447, 60 S.Ct. 321, 322, 84 L.Ed. 377 (1940) (footnotes omitted). Moreover, “[fjederal courts have an independent interest in ensuring that criminal trials are conducted within the ethical standards of the profession and that legal proceedings appear fair to all who observe them.” Wheat v. United States, 486 U.S. 153, 160, 108 S.Ct. 1692, 1698, 100 L.Ed.2d 140 (1988) (emphasis' added).
Inherent in our analysis is our conviction that the Sixth Amendment defect in this case would be so egregious if proved that “a presumption of prejudice [would be] appropriate without inquiry into the actual conduct of the trial.” Cronic, 466 U.S. at 660, 104 S.Ct. at 2047. As we reiterated in Swanson, “‘[Tjhe Supreme Court created an exception to the Strickland standard for ineffective assistance of counsel [which normally requires a showing of prejudice] and acknowledged that certain circumstances are so egregiously prejudicial that ineffective assistance of counsel will be presumed.’ ” Swanson, 943 F.2d at 1072 (quoting Stano v. Dugger, 921 F.2d 1125, 1152 (11th Cir.1991) (en banc)). In our judgment, this case falls squarely into the' exception described in Swanson. The alleged statements of counsel in this ease are too extortionate to qualify as the “assistance of counsel” required by the Constitution. See Holloway v. Arkansas, 435 U.S. 475, 490-91, 98 S.Ct. 1173, 1181-82, 55 L.Ed.2d 426 (1978) (prejudice presumed where a defendant’s attorney labors under a conflict of interest); Tucker v. Day, 969 F.2d 155, 159 (5th Cir.1992) (prejudice presumed where an attorney merely “stood in” during sentencing); Lozada v. Deeds, 964 F.2d 956, 958 (9th Cir.1992) (prejudice presumed where an attorney fails to advise his convicted client of his right to appeal); Javor v. United States, 724 F.2d 831, 834-35 (9th Cir.1984) (prejudice presumed where an attorney slept through portion of trial).
It could not be said in the light of such a proved outburst that counsel was acting “ ‘in the role of an advocate.’ ” Cronic, 466 U.S. at 656, 104 S.Ct. at 2045 (quoting Anders v. California, 386 U.S. 738, 743, 87 S.Ct. 1396, 1399, 18 L.Ed.2d 493 (1967)). Such behavior completely destroys and negates the channels of open communication needed for the relationship to function as contemplated in the Constitution. It is the client’s right to expect that his “lawyer will use every skill, expend every energy, and tap every legitimate resource in the exercise of independent professional judgment on behalf of the client and in undertaking representation on the client’s behalf.” Thomas v. Municipal Court, 878 F.2d 285, 289 (9th Cir.1989).
As a nation we have acted decisively to remove all vestiges of racial discrimination from our lives. Not for a moment will we tolerate racist behavior in our workplaces, schools, voting booths, and public accommodations and offices. With these accomplishments as well as the aspirations of our nation firmly in mind, we can discern no reason whatsoever requiring us to tell an accused too poor to hire an attorney to protect his rights that he must not only prove that his government-appointed attorney verbally assaulted him with racist threats, but that to obtain relief he must show some prejudice over and above such an inexcusable tirade. The improbability of such an outburst occurring between a retained counsel and, his client bolsters our analysis. The per se rule we adopt today may cost the government a conviction, but to hold otherwise would carry with it the unaffordable cost of tolerating what our Constitution and our laws tell us is intolerable.
Conclusion
Because we decide this case based on allegations rather than findings of fact, our opinion is necessarily conditional. Should the government continue to resist, Mr. Frazer shall now have the opportunity to demonstrate the truth of his allegations. Unless and until he does so, no stigma should attach to his previous trial attorney.
We note from his paperwork that Mr. Frazer is primarily interested in being resen-tenced with the assistance of a different attorney rather than contesting his guilt. These are matters best sorted out in the [786]*786district court when he has new appointed counsel.
REVERSED and REMANDED.
