No such thing - discrimination is discrimination. What it did do is attempt to frame the argument in such a manner so that the only people "capable" of discrimination are whites. As I've pointed out to several of my black friends, that's actually an insult to them because of the implication that they are incapable of discrimination. To say that is to say that they are less human than you or me.
You are correct, Adonius...good clarification on the “discrimination” comment.
