David Matthews, Author, Ace of Spades. Growing up as a bi-racial child, who could pass as either African American or white, Matthews says he knows first-hand how Americans can be racist. Matthews admits he slipped in and out of the black and white worlds, never really knowing who or what he was. Having a true identity crisis, Matthews says he swung from virulent white racist to pontificating black militant. As a guest on Sunday Morning Magazine, he revealed how he was treated differently when he was perceived as a black man as opposed to a white man.
