Here in rural PA, we do assume everyone’s armed, and we’re still not always polite.
Too many men around here are carrying more liquor than they can run with. I’m not against open carry but there will be casualties. Bad-tempered old boys behind every truck.
Heck, not too far from here and not many years ago, someone winged Santa in a Christmas parade.
So far I’ve not found anywhere I’d rather dwell. :)
We don’t see much of that - everybody keeps a low profile. Idiots just tend to go away and nobody ever asks where they went.
