I know a white AKA. It just so happened that when and where she was in undergrad there was a white Alpha Phi Alpha. People who didn't know them but knew of the white girl in AKA and the white dude in APhiA would automatically assume that they should be dating and would say so whenever they met one or the other. Something along the lines of "Hey, isn't there a white girl in AKA? You should date!" They were never interested in going down that road but found it funny, as do I.
As for the rest of it...let people have their opinions. Eventually (and it's going to be a looong time before we get there) race won't matter when it comes to matters of the heart, or any matter. But it's also important to note that there are still many communities in which interracial dating is seriously looked down upon. Like some others have expressed, I don't believe a healthy relationship could flourish in such an environment. Also, you have to think of the kids or future kids...if you are living in an environment that is hostile towards interracial dating/marriage, the kids (who should grow up feeling completely accepted, wherever they are) are going to take flak for it too.
As for me, I've dated black men (and I'm white). A lot of the times, the black women in the community would disparage the relationships. I've heard black women that say they want to keep the good black men to themselves
