Hay I wonder why, if THATS what the framers meant and only a MILITIA could have guns, that the citizens(damn near ALL of them) HAD GUNS WHILE THE FRAMERS WERE STILL ALIVE AND. OT ONE OF THEM SAID “Hey! It’s supposed to be for militias!”.
But if COURSE they didn’t. Because that’s not what it means.
In fact average citizens were able to purchase CANNONS.
The fact that you can't think beyond "truth is justified as true by the fact that it's been written on a piece of paper" may be pretty typical of religious fundamentalists, and not technically a mental disorder...
