Why did you add a comma between Arms and shall?
Also basic grammar. “the right of the people to keep and bear Arms shall not be infringed.” Is an independent clause. This is the right.
“A well regulated Militia, being necessary to the security of a free State” is a dependent clause and just provides reasoning.
Thats how I interpret it it too, If they only wanted just the militias to be armed they would have said the right of the militias to keep and bear arms, but they said the right of the people. This is and was intended to be the most prestigious legal document in their proto-country. I have to assume they used the language they did on purpose.
Except that every able bodied man was assumed to be a member of the militia. This is because the idiots who wrote the 2nd amendment didn’t want a standing army.
Then the war of 1812 happened and everyone was like “oh shit, maybe there was a reason why standing armies exist” and then the 2nd amendment was forgotten for a century. A bad idea that didn’t work out.
It’s kind of like the 3rd amendment. Important at the time, but actually meaningless in practice.
You say it was forgotten for a century as if people stopped buying guns for 100 years because there was a standing army. If the government wanted to get rid of it in favor of a standing army they would have done that, or at least tried. There’s no indication it’s a failed amendment because the US needed an army too. And in fact if it was a failed amendment, where was the uproar at the time? I don’t really recall any historical fight against that amendment.
