What question? Americans are literally misinformed, using propaganda to peop up their worldviews. See how it hurts you so bad to confront it?
Your shit question, was “how can the militia have guns” is pretty simple: the state owns the guns.
You didn’t even see my original point, which is that the government also defines the non-military members in the population, which is all males 18-45 and females in the national guard. If you actually believe in the 2nd amendment and the words actually written, those are the only people that should have the right to bear arms. No one else.
