At the time the 2nd amendment was written, “arms” had a specific meaning. There were no semi-automatic, or automatic, weapons.
Today arms include rocket propelled grenades. Do have have an absolute right to own a stinger anti-aircraft missle? That’s an “arm”, and you just said I have an inalienable right to keep and bear arms?
Is there ANY weapon I can’t have? If so, how do you decide which weapons are “rights” and which are not?
This is the same argument leftist gun-grabbers use (to be clear, I am *not* calling you a leftist gun-grabber -- just observing that you are using their argument). By this argument, logically we should only be permitted to own arms that existed during Revolutionary times. It's specious. The Founders were no fools. The answers to your questions lie in the Federalist Papers.
