Is Lost Racist?

I'll get to my important Imus opinion later. Right now I have a bigger question?

What the hell happened to Rose and Bernard on Lost? I mean, you never see them any more, not even in the background. Apparently if you're black on Lost, you either get killed, kill someone and then leave the island, or just disappear. I'm waiting for J.J. Abrams to apologize for his blatent racist actions. That is all.
