Baron Cohen has been criticised for the racist or prejudiced comments his characters have made (see "Da Ali G Show"). HBO spokesman Quentin Schaffer has replied to criticism concerning Baron Cohen's characters, "Through his alter-egos, he delivers an obvious satire that exposes people's ignorance and prejudice in much the same way "All in the Family" did years ago". Regarding his portrayal as the anti-Semitic Borat, Baron Cohen says the segments are a "dramatic demonstration of how racism feeds on dumb conformity, as much as rabid bigotry", rather than a display of racism by Baron Cohen himself. "Borat essentially works as a tool. By himself being anti-Semitic, he lets people lower their guard and expose their own prejudice", Baron Cohen explains. Addressing the same topic in an NPR interview with Robert Siegel, Baron Cohen said, "I think that's quite an interesting thing with Borat, which is people really let down their guard with him because they're in a room with somebody who seems to have these outrageous opinions. They sometimes feel much more relaxed about letting their own outrageous, politically incorrect, prejudiced opinions come out".
