Yes, why would the founders create a second amendment to enable "treason" when treason itself was mentioned in the main body of the Constitution? What, you have the right to bear arms but direct those arms toward the government and you will be convicted of treason?
The purpose of the second amendment is clear if you know anything about American History. The founders had a real fear of standing armies, and for good reason. Just read the Declaration of Independence. And I noticed you ignored Article I, Section 8, a real protection against a standing army. And therein lies the purpose of the second amendment, to provide for a "militia", I mean the perfunctory clause ain't there for shits and giggles, to stand at the ready instead of having a standing army.
The second amendment wasn't about personal defense, hell, when it was written most townships required, you got that REQUIRED, residents to keep their arms at a centrally located armory. Much like our Grandma example, residents were more likely to be overran by Native Americans and their guns stolen than they ever were of holding them off. Muskets against skilled archers, not much of a contest. Hence the requirement of having them at the armory. And yes, in regards to the Battles of Lexington and Concord, the British were on their way to the armory in Concord. I mean hello howdy. The minutemen went to the Armory, got their guns, and waited on the British. Not like they grabbed them from under their damn bed.
And hunting, give me a damn break. The colonists sucked at hunting. The idea that they went out and shot their dinner is a flippin joke. Hell, more likely they traded their damn musket for dinner. Daniel Boone was an anomoly, much like my great, great, great, great grandfather, who made a fine living "hunting" and spoke Cherokee and German, no English. If everyone could hunt he wouldn't have been able to build a fortune.
And there is gun control. Guns were outlawed in most Western towns, you had to check them in with the local sheriff when you entered town. What the hell you think the shoot out at OK Corral was about? I mean the shit starts getting ridiculous. The gun lobby has completely revised history for their own profit motives, the number of children and others killed be damned. It is time this shit came to an end.
