Well OP. If that’s true you should be able to find yourself a 2/3 majority and get it repealed. There’s a process for that built right into the system itself. Though as recently as WW2 (the last time a land invasion of the mainland US was even considered) the second amendment and the rate of civilian gun ownership was cited as a major concern.
i don’t disagree that part of its purpose was to have a safeguard against a standing army under a tyrannical govt. however, local militias and personal weapons made it significantly easier to put down slave rebellions or lower class protests towards the ruling class, which is a significantly less spoken about but no less historically significant facet
Brother, I think you got the communist manifesto mixed up with your federalist papers. The purpose of the second amendment was not to put down rebellions of the working class, the second amendment was meant to arm the “working class” so they couldn’t be put down so easily. Why would you give the majority of people military grade weapons to make it easier for a minority to oppress them?
