re: #73 ggt
IIRC, when the Constitution was formed, there was no provision for a standing army. Therefore a “well-regulated militia” was national defense. This is the argument of the gun-control advocates.
I think the idea of armed-citizens who will defend their lives, their familes and their property makes for a government respectful of the powers that have been delegated to them.
It’s a different (perhaps American) mindset than what much of the world has.
I would say that the thought-process goes back even farther than that.
