I would have voted yes with no caveats if that option had been available. Humans are naturally racist. It's a survival mechanism.
I've seen some people in this thread state things like "children are not racist", and that makes racism unnatural. I disagree. Children adopt the racist ideals of the society in which they are raised (as long as they are accepted in that society). I think it's flawed to call that unnatural since the phenomenon exists in all societies.
