The basic, irreconcilable issue is that the Founders intended citizens to be dangerous. The Bill Of Rights specifically and clearly documents their intent to establish a nation in which the citizens are armed and dangerous. Dangerous people are harder to control and oppress.
An obvious consequence of having dangerous citizens is that some will go crazy or choose to be criminals, and inflict damage, injury, and death upon other citizens. It’s equally obvious that the Founders understood this obvious consequence, and wrote the 2nd Amendment anyway. Clearly, they felt the benefits outweighed the risk.
Gun control - specifically bans and additional punitive taxes levied to limit acces by the poor - is an effort to make citizens less dangerous. This aim, and that of the Founders, are diametrically opposed. If gun bans are what you want, the answer is to amend the Constitution to repeal the 2nd Amendment, not pretend it means something between what it actually means and what you wish it means.
The Constitution provides a clear legal mechanism for amendment. It’s been used before. If you think the 2nd Amendment is a dangerous historic relic, repeal it.
But quit pretending that the purpose of the 2nd Amendment is to protect hunting and sporting guns. Quit pretending that it doesn’t protect an individual right to possess weapons comparable to those carries by the nation’s armed forces. When the British marched on Concord to kick off the Revolutionary War, they weren’t going to confiscate pistols and flintlock muskets - they were going to confiscate artillery. This was THE eventuality the 2nd Amendment was written to prevent.
Be honest, and if you want to strip the people of the right to own weapons, join or start a movement to repeal the 2nd Amendment.
Or if you’d like to do something short of that, yet consistent with the Constitution, maybe ask how existing Constitutional gun regulation could be better enforced. This person had been convicted of felony domestic violence. The system failed here, but the point of failure wasn’t the Bill of Rights.
