President Barack Obama!

Try telling the US that they have another valid white President.

I never said he was white, just that if you are going to say he is black it's just as valid to say he is white.

The name black clearly come along because people originating from African people have black skin however plenty of people from parts of India have black skin, but are not referred to as black.

Black is used to refer to ethnic groups of people originating from Africa.
White is used to refer to ethnic group of people originating from Europe.

A black albino is still ethnically black. Their skin may be white but they are still black.

Obalma has one white (europen) parent and one black (African) parent. So to say he is white is just as valid as saying he is black.

I have nothing against people calling a black man a black man or a white man a white man when it is true. People seem however to have a problem with calling someone mixed race, or mixed or what ever though as if it's some how an insult.

EDIT: I agree with Baki that just not white is the significant part in terms of historic politics and it will be years before it will be really possible to judge whatever the policies what he puts in place.
