Maybe you should add an "Insured by Smith & Wesson" bumpersticker. People might think twice about harrassing you. ; )
No doubt. Add a pocket Constitution from the CATO Inst. and a Bible or Christian magazine in the car and you'll fit the FBI profile of "domestic terrorist."
fingering the wrong person, will get you in trouble. but it should still be allowed... as a speech issue...
No question of disallowing it here. It's not the same as desecrating the American flag IMO. But you are quite right about crossing the 'wrong person.' Out west, at least, a lot of Harley type bikers are quite conservative politically. It wouldn't be too strange to see a Bush/Cheney sticker on one of their four wheeled rides. Guys like that often have a low tolerance for disrespect and a rather unPC concept of how to respond to it.
