I don't think it's racism tho. Honestly, the only people who find it "racist" are blacks who want to date white people but have little luck.
sss it's interesting that gay men deal with this too tho. I always see black women complaining about this. Particularly, from white men who don't want to swirl.

Personally, it has never bothered me because I have my own preferences, as well. It is what it is. I'd be more alarmed if someone said they only date outside of their race and have no interest in their own. Like that's clearly a fetish or you like being fetishized. Like white guys who are down with the black girls seem to have a slave/massa complex or black guys who mess white twinks (hey nick luv) are being used for their dicks lolz.
