Is Barack Obama an African American?

A lot of people ask the question about is Obama black. I don't care what anyone says but to me he is. Though he has a white mother, his dad is a black african man. So he is just mixed, just like mostly every other light skinned person that we still call black is. If he was back in the day, he would be a slave because of his skin color. If he isn't black then what is he? If you have to question his race then obviously he is. If he isn't black then I really wonder why is he trying to help us so much. If he isn't black I wonder why the world feel this is such a big movement for him to become a president, because they say its history. It's history because he is the first black president. His wife is black, they made black kids, and their culture is those of black people. Many people even got mad when him and his wife dapped each other hands, something that blacks do. Its just to many things that they do that can't even make me think otherwise and neither should anyone else.
