Had I informed this woman that when she pushed my son, she was acting according to a tradition that held black bodies as lesser, her response would likely have been, “I am not a racist.” Or maybe not. But my experience in this world has been that the people who believe themselves to be white are obsessed with the politics of personal exoneration. And the word racist, to them, conjures, if not a tobacco-spitting oaf, then something just as fantastic—an orc, troll, or gorgon.
