Wasn’t bringing your guns to church a frontier tradition back in the day? Simple good manners and common sense when injuns or bandits might strike at any time?
I’ll leave aside the Southern feuding tradition, a la “Huckleberry Finn”.
my father in law does. it’s a big church and he teaches kids in sunday school. they actually have cops at the church and they don’t have to worry about going downstairs they know my father in law is taking care of business
