Well, if you go by the old southern "one drop of blood" bit, I'm Black. On the other hand, appearance wise, I make a Scandinavian like Chris look African. (Okay, maybe that's a bit extreme!) Plus I was raised with no knowledge that my great-great grandfather was the black sheep of the family in more ways than one. You tell me what I am; I haven't a clue.
On the other hand, I don't understand why people get so bent out of shape when this question is asked. Perhaps those screaming 'racism' should look within once in a while...
