You have zero ground to stand on with this argument. As been shown by both Miller and Heller. The first part about the militia, is the prefactory part of the 2nd amendment. It's not the objective clause. Grammatically speaking, it does not stand by itself without the objective part. Of which, the objective part does stand on it's own. That second comma was originally a semi colon for a reason until a scribe fucked up in the original copying of the BoR into the Constitution. It was well understood that one couldn't have a militia made up of citizenry if the citizenry could not keep and bear arms individually as an individual right.
The text originally agreed to by the House
"A well regulated militia, composed of the body of the People, being the best security of a free State, the right of the People to keep and bear arms shall not be infringed; but no one religiously scrupulous of bearing arms, shall be compelled to render military service in person."
The text originally agreed to by the Senate
"A well regulated militia, composed of the body of the people, being the best security of a free state, the right of the people to keep and bear arms, shall not be infringed, but no one religiously scrupulous of bearing arms shall be compelled to render military service in person."
So your crap about a semicolon being a scribe error is bull.
From Miller decision:
"In the absence of any evidence tending to show that possession or use of a 'shotgun having a barrel of less than eighteen inches in length' at this time has some reasonable relationship to the preservation or efficiency of a well regulated militia, we cannot say that the Second Amendment guarantees the right to keep and bear such an instrument."
and
"The significance attributed to the term Militia appears from the debates in the Convention, the history and legislation of Colonies and States, and the writings of approved commentators. These show plainly enough that the Militia comprised all males physically capable of acting in concert for the common defense. 'A body of citizens enrolled for military discipline.' And further, that ordinarily when called for service these men were expected to appear bearing arms supplied by themselves and of the kind in common use at the time."
Now the Miller decision supports some of what other posters said, but not you. And in fact does mention that a firearm need to have a "reasonable relationship to the preservation or efficiency of a well regulated militia".
If you're going to lie you should do a better job or do it someone not significantly fucking smarter than you.
