Angry Black White Boy is satire, so its plot should be understood ironically, as if Mansbach is making fun of the characters for their behavior. The plot follows the efforts of a Jewish boy to feel "black" instead of feeling his white guilt. Macon Detorny is a Jewish kid from Boston whose first-hand account of racial injustice leads him to dislike the Beastie Boys and white culture in general, paying attention to the small, consistent ways that injustice still exists within white culture.
When Rodney King was assaulted in the LA riots, it was a breaking point for Macon. This causes a dilemma within himself, and his verdict is that he deserves to be punished for the sins of his race, but when he goes to the street, there's no one there to beat him up. Instead he decides to invent a riot, since there isn't one where it should be. To start the riot, he throws a flaming trash can at a police car, and the car burns, but it doesn't start a riot. He feels that his efforts have failed because he was too white to start a riot.
Macon's passion, combined with his confusion around his own identity, lead him to become radical. He terrorizes white passengers in his taxi cab at gunpoint, in order to exact revenge against them for being too white. When he arrives at college, he finds that his roommate is black, and he can't help himself but to try to impress his new roommate. He even shows him the tattoo on his arm of the King verdict in '92. It turns out that the roommate was actually in the riots. This kickstarts the beginning of Macon's struggle to find his own identity.
In school, Macon encounters an academic version of his own misplaced white guilt. Macon becomes influential for his studies, and his institutes a new holiday, the "Day of Apology" when white people are supposed to come into the "hood" and apologize to specific black people for their white guilt.
