Why do so many races ask stupid questions about black people?

I'm Serious. Here are just a few I saw on the net why do black people like fried chicken and water melon? how come blacks have lighter skin on the front of their hands? are black peoples brains smaller than white peoples brains? Do black people get sun burnt? WTF?? why the hell are you so concerned about what we eat and how we look anyway!!! You think black people wake up in the morning and wonder Damn I wonder why white people are so white??? I dont. I couldnt care less. The point is that I think that people are so concerned with our differences that we forget just how similar we are. If I punch you in the eye and you punch me in the eye were both gonna get a swollen black eye! so why ?
