What it doesn't mean.
The right to bear arms is not the right to carry guns around with.
The right can also be infringed. These are the two most common mistakes people make.
The right to keep arms is the right to own guns. The right to bear arms is the right to be in the militia. The 2A prevents the US federal govt (and now state govts) from preventing you from being able to own arms, this does not mean they can't ban certain weapons, just that you have to be able to get guns, and the they can't prevent you from being in the militia, hence why the made the Dick Act and stuck all males aged 17-45 in the "unorganized militia". Rather convenient.
the right to bear arms has nothing to do with a militia
the militia is secondary to the right to keep and bear arms
Well, you're wrong and I'm going to prove you're wrong.
Amendment II: House of Representatives, Amendments to the Constitution
This is a document from the debates in the House on the future Second Amendment.
Mr Gerry said: "Now, I am apprehensive, sir, that this clause would give an opportunity to the people in power to destroy the constitution itself. They can declare who are those religiously scrupulous, and prevent them from bearing arms."
This was about a clause of the future Second Amendment that read: "but no person religiously scrupulous shall be compelled to bear arms."
Then Mr Gerry said: "Now, if we give a discretionary power to exclude those from militia duty who have religious scruples, we may as well make no provision on this head."
Yeah, the same person used "militia duty" and "bear arms" synonymously. Go figure.
Then "Mr. Jackson was willing to accommodate. He thought the expression was, "No one, religiously scrupulous of bearing arms, shall be compelled to render military service, in person, upon paying an equivalent.""
So, we have "render military service", "militia duty" and "bear arms" all meaning the same thing.
In fact in different versions of what would become the 2A, "bear arms" and "render military service" would replace each other.
June 8th 1789
"but no person religiously scrupulous of bearing arms shall be compelled to render military service in person."
August 17th 1789
"but no person religiously scrupulous shall be compelled to bear arms."
August 24th 1789
"but no one religiously scrupulous of bearing arms shall be compelled to render military service in person."
August 25th 1789
"but no one religiously scrupulous of bearing arms, shall be compelled to render military service in person."
So, it has a lot to do with the militia, actually.
But then, I'm willing to see what evidence you have, though, I do have a lot more to go on than just this, this is just a start...
