I had the strangest accusation of racism over this once, but guess I should tell the story...
Was in the pub with a few mates chatting away and the topic came up of people you find attractive, as the conversation rolled on I mentioned having a weak spot for black girls, even more than white girls, something about their skin I find makes them so beautiful... and yes I do realize how creepy that sounds, its hard to put it any way without it sounding creepy.
Anyway as I told this to my friends this black guy wandered over to our table and starting going off on one. Calling me a racist, to stick to my own race, that I'm a bigot and the only reason I'm attracted to black girls is some lingering racist sentiment and wanting to "dominate" another race like my ancestors apparent did during the slavery era.
Confused the hell out of me, how on earth does finding black women attractive as a white man and wanting, if the opportunity arose, to be in a consensual relationship make me racist just because I'm white, still baffles me to this day!
Still I guess that answers your question too, I have nothing against dating outside of my own ethnicity/race, would prefer it in my case given my preferences. Love is love and people are attracted to who they are attracted to.
