This is a pretty funny bit, but 99% of people just see this bumper sticker and think "Another MAGA fuckhead". There's committing to the bit, and then there's whatever this is.
If you live in like a 90% red area, this is pretty solid camoflage. Then the MAGA fuckheads are less likely to mess with you, but you're not actually offering support.
And on top of that, someone who meets you could get the wrong idea.
If i met someone who had this i would immediately write them off and never bring it up.
Also couldn’t you just not have any bumper sticker? Isn’t that sufficient “camouflage”? Or if you are not actively defacing your own property you are a libtard?
