Apparently, on the flip side, suppose you are white and only date black women. Are you still racist? Am I a racist or homophobic because I will only date girls and not men?
This is similar to men who only date blondes. They are Male Chauvinist Pigs. However, there are men who say they date only intelligent girls with whom they can carry-on meaningful conversations. They are said to be enlightened.
It seems to me, that you are racist if you discriminate against the "race" that is not politically correct to discriminate against. If you discriminate against a class which is not "weak" or "underprivileged" - society gives you a pass.
To end with Seinfeld : "If I like their race, how can I be racist"
