I agree with Phreak, if you were racist, you wouldn't be worrying. Most people have their preferences with skin color. Personally, I'd prefer to date white/caucasian/european people, but I've also have had feelings towards people with different skin colors. No matter what your skin color, there are people who prefer to either date people of their own skin color or a certain skin color, and there's nothing wrong with that. It doesn't make you racist, it's the same as people wanting to date someone taller or shorter or younger or older than they are.
