The 2nd amendment literally doesn’t provide them the right to a weapon.
If it did, particularly for the reason they say, literally killing a politician would be legal if you could prove “their tyranny”. That’s the biggest load of bullshit.
It’s a simple provision that provides the States with the right to arm their own militias.
So many chode Americans believe “theyre the miltia!!!”. The government also defines that, though, and it’s … not everyone. Its only males 18-45, and women in the Guard. That’s it. So the only people the 2nd amendment could even begin to logically and legally allow a weapon are healthy, able bodied males 18-45 and trained women. And they don’t really need to prove theyre able bodied, so every fat guy with a gun is breaking constitutional law
Almost everything you said is correct, but you forgot that a militia is not a military organization, they are paramilitary and are still civilians. Legal definition of a militia does not mention requirements of age or health. National Guard is a military organization that is funded by public tax dollars and mandates specific ages and health.
Because of this fact, militia are only mandated by the US Constitution to be "well regulated" so that when a state governor calls them to action, they need to form and follow a chain-of-command, which requires the ability to train with their firearms on their own personal time and their own dime (they are legally not allowed to be a burden to the taxpayers in any way, unlike the state National Guard).
So this means unrestricted access to commercial firearms and the freedom to train on federal land or private property with their own personally owned (not government issue) weapons.
