One article describes Mansbach as, "a nice Jewish boy from Newton, MA, " and talks about his budding interest in black culture, "Mansbach spoke about his own early attraction to black culture, when he’d ride the bus that brought black kids to his heavily Jewish suburban school back to their African American neighborhoods to hang out and listen to the music that meant more to him than the Hebrew school he was thrown out of. "
The comparison between Mansbach and Macon is very clear. They are both jewish boys from the suburbs of boston who got into hip-hop and rap. The difference is very clear when it come to their interactions with the culture they so dearly admired.
In the novel, Macon seems to trample any black people who have an opinion contrary to his and uses hip-hop as an invisible badge of cultural knowledge that gave him the right to say and act as he wants. The first example of this is him not correcting the media when the news of a black cab driver robbing white passengers gets out. Macon does not consider the possibility that he is hurting the black community much more with his actions than the white community. The second and perhaps most obvious example of Macon's righteousness comes when he dismisses all the other voices at the Black Student Union and decides that he knows best for the group.
Mansbach, however, deviates from Macon in this respect. Mansbach recognized that he really wasn't a part of the culture and owes most of his "hip-hop insider knowledge" to his participation in hanging out with the inner city kids whom he met on the bus. Mansbach spoke about his time with his new friends as, "venturing outside of comfort zones, rendering myself visible as different."
With this history of Mansbach, it seems that the novel could not be anything but a satire of an alternate version of Mansbach himself, but his recognition of the person that he could become is all the difference between clueless hypocrite and a great book writer.
