It's true that being "white" is not an identity at all, at least in America. It just means you're not black. It's a purely exclusionary identity, standing for nothing else.

The implication for this is that you can't just take any black liberal's words, replace "black" with "white" and vice-versa, and then presto, the speaker is a racist.

My point is not that blacks can't ever be racist, but that you can't expect blacks to talk about being black the same way whites talk about being white.
