Why do I only attract black guys?

I'm 5'3, 115 lbs, and pretty damn fit. I am half white half mexican with long, dark wavy/curly hair. I have been told by numerous people that I am a very attractive women, but the only guys that seem to want to talk to me are black guys. Not that I have a problem with black guys, I like my chocolate ;) but I was just wondering why white guys never seem to want to talk to me. Well, white guys talk to me if they're drunk, but typically not when they are sober.

Anyway, my question is why won't white guys try to strike up a conversation?
