On another note, when she said Jesus was a white guy, it's a completely different story because Jesus was in all probability, a brown Middle Eastern man and she's just ignoring history.

Jesus was no less white than any other Jewish person is. If he were alive in 1960s America, he'd be able to vote, use public facilities in the South and attend most private universities, but would probably be too "ethnic" to get a membership at the local country club.
