I can promise you every single black dude has wanted to be white once in his life to get rid of all the prejudice and discrimination etc =)
Oh please...as if being white means anything past being able to exist by yet another set of prescribed societal rules. Whites do not experience prejudice or discrimination? C'mon...
The problem with humans is that they believe in external factors to define themselves as better, freer, smarter, etc. The reliance of those external factors are what holds humanity back from true greatness. In essence, being white can also affect the potential for one to 'rest on their racial laurels' in an arrested development of a sort.

On the Sosa situation, he's a tool. It kills me...the only winner is the cosmetics company that sells the bleaching and tanning products. On one hand, they sell brownies the ability to lighten their skin. On the other, they sell pinkies the ability to darken their skin.
