How many people on Yahoo has rejected a guy or girl because of their race?

"but it's only a preference" That's all I hear is the only excuse. So if preferences aren't racist even though you're "preferring" one over another due to skin complexions. Is it also just a "preference" if I said I rather only associate with people who're white? I don't in general but if a white person said that, well, they'd probably get sh*t for it! If someone did reject someone because of their race, why don't they tell them so? They don't have to be mean they can just say "Im not attracted to you because......." you're white, black, latino, oriental" etc. Anyone. Anyone. Oh anyone at all!
