It's only the in past few decades that the Second Amendment has been perverted into the right to carry any gun you want where ever you want.

>the Miller Court unanimously concluded that the Second Amendment did not apply to the possession of a firearm that did not have “some relationship to the preservation or efficiency of a well regulated militia.” And in 1980, in a footnote to an opinion upholding a conviction for receipt of a firearm, the Court effectively affirmed Miller, writing: “[T]he Second Amendment guarantees no right to keep and bear a firearm that does not have ‘some reasonable relationship to the preservation or efficiency of a well regulated militia.’

"In reality, the district court judge was in favor of the gun control law and ruled the law unconstitutional because he knew that Miller, who was a known bank robber and had just testified against the rest of his gang in court, would have to go into hiding as soon as he was released. He knew that Miller would not pay a lawyer to argue the case at the Supreme Court and would simply disappear. Therefore, the government's appeal to the Supreme Court would surely be a victory because Miller and his attorney would not even be present at the argument....Miller was found shot to death in April, before the decision had been rendered."
Myself, I think 2A is just an anachronism. Militias as they were at the founding don't exist anymore. Almost no one in modern US society meets military readiness standards. Armed forces use bonkers weapons of war the founders could never have imagined. Even individual person-on-the-street weapons are pretty boggling by 18th century standards. And this is just considering firearms, expanding "arms" to whatever the US military considers to be a weapon (software/hardware exploits, biological weapons, chemical weapons).
Further, I think "2A as a check on government" is meritless because Congress regulates militias, and the Constitution (Article I, §8) reads: "The Congress shall have power to... provide for calling forth the militia to execute the laws of the union, suppress insurrections and repel invasions." Allowing governments to suppress insurrections is the opposite of allowing checks on government.
I'm not like, super into gun control--I think the US is too big for a one-size-fits-all policy and I think a lot of implementations just land men of color in prison w/ felonies. But none of the pro-gun 2A interpretations make sense to me, and from where I sit the debate is more a reflection of Congress' ongoing slide into irrelevance and sclerosis as other less encumbered institutions in the US do the actual legislating.
So to me, that kind of means the terrorists win. China/Russia would like nothing more than for that to happen--it would be a self-inflicted wound of insane magnitude, with global consequences. I don't know that any political issue is so bad that it's worth solving at that cost. Maybe climate change, but the groups of people who are heavily armed and the groups of people who care about climate change are mostly separate.
So I still think 2A is an anachronism. I'm not sure even TJ would agree that refreshing the tree of liberty at the cost of the west makes any sense at all. The world has just become unrecognizable in the last 250 years.
