Its complicated and I have opined about the 2nd amendment here over the years... I am not as good of a mind reader as so many here but it appears our founders were concerned about preventing the central federal government from gaining too much power over the states, and viewed state militias as a counterbalancing force.Still no challenge, other than to look toward history (not directed toward me), but I’m unaware of a true apples to apples comparison. I’m looking for a convincing argument based on something, rather than just saying it’s so.
Guns for self defense (and hunting et al) was not enumerated as a constitutional right or even considered because it was very likely considered a "natural" right.

These days one driving motivation for personal gun ownership is a breakdown in justice and policing. Releasing violent criminals back onto streets without punishment just empowers them to break the law again.

It is common sense that psychotic, unstable, imbalanced individuals should not have access to force multipliers (like semi-automatic weapons). Some states are having modest success with red flag laws but these are still relatively new so not much track record to assess.

PS; It is perhaps interesting that former prime minister Abe was assassinated with a home made gun. Japan has very strict gun laws.
