He calls himself African American...I always took that for black.
He can call himself whatever he likes. He is more white and Arab than he is black. His family owned slaves and he shares little if anything with the average American black person; grew up in Hawaii and Indonesia, raised by white relatives, went to private schools, had two foreign citizenships, did not experience racism and benefited from being a foreign student, to name but a few....
He may say he is black, but he ain't black.
