Don't leave them on your car when you park at stores. I keep mine in my glove box - put them on my doors when I'm driving, then when I arrive at my destination, take them off and put them into the glove box.
My only other sticker says 'Obama Is A War Criminal' and it has his stupid O symbol with a line through it. It's an actual bumper sticker though, so hopefully no ignorant fool decides to do damage to my car here in Atl. I sure get some different looks for that sticker, lol.
It may confuse or shock some people, but it's true. Though, I think it would sound better as "warmonger" than it does as "war criminal."
I think we can get more on board by showing that Obama is a warmonger and Paul is not.
