That's something I don't understand, though.
I'm not very attracted to black people. That's not because I think they're lesser, or even uglier in any ways - I just don't find them sexually/romantically attractive. I think they're beautiful, nice to look at like art, but I don't find them attractive in that way.
This doesn't make me racist. Just like homosexuals aren't sexist, they just aren't attracted to the opposite gender.
