There has never been a democracy that has not evemtually committed suicide. Without constitutional rules, a nation is doomed.
As a rule successful government breeds a population that is law abiding and in short “civilized”.
Any successful form of government constitutional or not.
Such societies tend to collapse when a dictatorial regime or less civilized society comes along and needs the resources of the more successful society.
The difference here is that a large number of Americans are armed - if they retain their freedom depends on how many of them will be less law abiding.
When someone else’s right to be unarmed conflicts with my right to keep arms, they and their laws can go to hayel.
