Heh. I know it's a topic astray from the thread, but there is no doubt in my mind that the Congress and Courts would have no more trouble infringing under that statement, than they did and do with the "well regulated militia" clause being in there too.
Wave the hand and redefine "arms", like Scalia did in the Heller case, to mean "arms in common use." Or redefine "infringe."
"Law" and "logic" are emphatically not the same thing. Law is what is enforced by the credible threat of force, death if you push hard enough. It's little more than brute force, couched in what its practitioners fancy to be righteous justification. But at bottom, it's nothing more than brute force. See, e.g., Mafia. Same thing, different name.
I see your point, in the end, it all comes down to what we believe is right, under our own rules....mine are based in God and freedom.
Any way you look at it, the one who is best able to defend their belief will win, no matter the weapon.
