Referenced by Tressie McMillan Cottom in a recent article; the thesis seems to be that whiteness as an identity is a powerful political force distinct from and in addition to out-group hatred. I'm not sure I understand what it means for a dominant group's identity politics to operate distinct from hatred of the Other, and if this reference had come from an author I respect less I might dismiss the idea, but given the context I want to learn more and try to understand it.
