There is nothing inherently wrong with liking your culture or "tribe", but rather that is natural. As a WASP, I don't care if you are a proud Black or Asian or what ever, it makes no difference to me, but why can I not be a proud White, with out being racist? I actually love it when someone calls me racist, because then I can just point to my Asian wife and 50/50 kids, and say really?
I hope that one day, we in the US, will start to see each other as Americans first, then we can start to put this crap behind us.
