Geez. What is he if he ISN'T Black? Leopard print?
As soon as there's a bi-racial baby, everyone wants to try to tell them how they should identify themselves. If Obama wants to identify himself as a Black male, fine. Honestly the majority of bi-racial kids I knew lumped themselves into the Black category, which was fine. And those that didn't try to identify with a race.. that was fine as well.
I think people need to stop trying to say if you aren't 100% Black, then you aren't black or if you aren't 100% white, then you aren't white. That's why so many bi-racial kids always have such a hard time growing up.
My family tends to be staunch against "racial-mixing" and after this, I can see why. (Though I don't really give a damn and I'll continue to enjoy dating outside of my race

)
It's kinda like that episode of Family Guy, where Stewie was conceived by Nate Griffin and Lois LauraBushCheneyPewterschmit and Stewie says something on the order of, "Since I'm half black and half white, now I'll be accepted by both races."
In the end, nobody's really going to accept you, racially. Especially when people aren't as colorblind as they think.
