Adam Mansbach offers Angry Black White Boy as a satirical criticism of the state of race relations. He notes that the dominant perspective is seriously flawed, because it is driven by white progressivism instead of being driven by justice and equality of opportunity. Thus, the novel offers a ridiculous hero with a baffling anger issue who characterizes the farcical state of "social justice" efforts in America.
One obvious reason for why this is the case is because Macon, the Jewish activist in question, has been miseducated about the problem. For Macon, the problem is white privilege and white guilt, whereas for black people, the problem is real injustice and inequality of opportunity. So Macon targets white people as enemies of justice, as if to say, "Oh, black people aren't evil, white people are." Instead of aiming for community and equality, Macon has traded one racist attitude for another equally racist attitude, one that provokes him to nearly murder innocent strangers, just for being white.
Ultimately, the final joke of the novel is its most blatant attempt to show the difficulty of sustaining racial reconciliation done from a position of white guilt. Macon institutes a new holiday after gaining a little traction in his activism. The holiday is called "The Day of Apology," and it's Macon's best solution for racial disparity. On that day, white people are supposed to drive into the ghetto and just start apologizing to black people for their racial history.
There is the central idea of the novel. No one was asking for apologies, and yet Macon's only solution is just to say sorry. Instead of creating equality of opportunity, he merely finds a way to get white people off the hook instead of doing the hard, slow work of fixing systemic injustice.
