Yeah, I have to agree with ulimamax on the race issue there.
I personally would probably not date a black person, because in the large majority of cases, I don't find any black women attractive. But the reason isn't the skin colour, which I think can be lovey, but rather it's the facial features that are common among black people. I'm not attracted to the larger lips and flatter, often wider noses that are common. These same features can also be found in white people, but less frequently, and I wouldn't be attracted to them there either.
That's not to say that I might never find a black woman who I'm wowed by her beauty and in love with her character.
But as the record currently goes, I've not met a black woman I've been attracted to.
So, as it goes I wouldn't want to date a person of another race (or at least a black person) because I've never been attracted to them. What would be the point in dating someone you weren't attracted to.
