Ditto on the NRA stickers. I have reluctantly stopped putting ANYTHING on my vehicle that could be construed politically. In NE urban areas, NRA decals (or any “gun related” decals, and nowadays the Gadsen flag) WILL get you pulled over and hassled by LE. Political stickers invite vandalism or worse. I nearly lost my job once over a bumper sticker (small-town politics...a long story, not so interesting in retelling), and others I know have had cars torched or shot at.
When I was a kid in the late 70s, my dad had a huge bumper sticker on his truck that said in white letters on a red background “More people have died in Ted Kennedy’s car than in Nuclear Power Plants”. That got a few scowling looks even in a small midwestern town. I can only imagine the horror with a sticker like that in New England.
