You've missed the one bumper sticker I've seen designed to piss almost ANYONE off:
"Nuke the unborn baby gay whales for Christ".
And the guy who was selling them, told me he sold 5 or so of them per week. . .
in high school i had an Einstein quote about furthering nuclear power for the bennefits of mankind and a "go nuclear, go navy" sticker on my car. i had alot of people thinking i was contradicting myself, but i assured them that i wasnt.
