If Donald Sterling is so racist, why does he have a black girlfriend?

Because it is easy for white males to fetishize and exotify black women (in a way that could be mistaken for romantic affection) and simultaneously criminalize black men. Sterling is threatened and insulted that his black girlfriend could recognize a black man’s worth….it challenges his prejudice and her can no longer depend on his “superiority” to quiet his insecurities about her relationships with black men.

At the end of the day both are objectified and stigmatized.
