All rights have limits. But the Founding Fathers probably didn't envisage the modern world where we'd want people who had been criminals barred from legally owning weapons. They didn't have massive cities, lots of people live in the countryside, or the countryside was really close and lots of people went hunting. They also probably didn't consider mass murder of innocents very much either.
They did, however, envision the more general possibility that the certain conditions of society might change, or certain provisions of the Constitution might not be found to work, and that there would be a need to alter the Constitution; so they set forth a procedure for doing so. By wise design, this procedure is not trivial, and not to be undertaken unless there is very strong, clear public support for it. In the time the Constitution has been in effect, and not counting the Bill of Rights, this procedure has successfully been invoked seventeen times.
If the time has truly come when the right to keep and bear arms should no longer be upheld and protected against any government interference, then the correct way to address this would be to ratify a new amendment to the Constitution, which supersedes the Second Amendment, and which establishes the necessary authority on the part of government to impose restrictions on the people's possession and ownership of arms.
It is absolutely not proper to enact legislation or executive orders which directly contradict the Constitution, nor to get corrupt courts and judges to rule that the Constitution does not say or mean what it very clearly does say and mean.
If you want to restrict the people's right to own and carry arms, do it properly, by way of a Constitutional amendment. I've seen polls claiming up to 90% support for some such restrictions. If that support is really there, then there's no reason not to try to do it the right way. With 90% support, an attempt to amend the Constitution would almost certainly succeed.
What I suspect is that those polls showing such high support for such restrictions are bogus, and that those in the gun control movement know it; that they have not undertaken to try to get a new amendment ratified, because they know that those polls notwithstanding, there is not actually nearly enough support for such restrictions to give any attempt at ratifying an amendment to this effect any reasonable chance of success.
