Our so called "preferences"

I'd say in most cases that's what it has to do with. Lookin in the 80s, all you saw on TV as far as actors and R&B singers was light skinned foos wit jheri curls, and that's what girls liked. In the last few years, you've seen darker dudes, usually corn rows or low cuts, and a lot more "thugs" or whatever, and that's what girls like now. Same with dudes, all you see in music videos is mixed lookin girls with long **** hair, and that's what most dudes seem to like the most.
