Lots of people talking about the on-going "gun debate."
(smh)
There is no gun debate.
The gun issue was settled in 1791.
Some people get it, some don't... that's not a debate, it's just a failure of education.

We have changes to make... but not to the Constitution.
The Constitution is just about the last remaining vestige of the "last best hope of earth", once a beacon of possibility for oppressed people all over the world. That beacon has been dimming Progressively as we continue to turn away from the principles that illuminated it in the first place.
This problem is cultural, not legislative. We can't pawn it off on Trump or Congress to fix; they can't.
Only we can.

As John Adams reminded us in 1798:
“We have no government armed with power capable of contending with human passions unbridled by morality and religion . . . Our Constitution was made only for a moral and religious people. It is wholly inadequate to the government of any other.”

Self-governance demands that we all have at least a working understanding of our founding principles; where they come from, how they were both embodied and preserved in a governing framework, and why.
A people who don't understand their own core principles cannot possibly preserve them against relentless assault from both power mongers and from a frightened herd who sees a problem but has no idea which way to run. The Constitution shows us which way to run.
The root of our problem, and therefore the solution, is in education.

America has been in a steady cultural decline since, and to the extent that, we've allowed the nationalization of learning institutions into nothing more than State-run education camps.
The State has priorities of its own. Bureaucracy naturally works only to preserve and expand itself. That doesn't take any conspiracy, that's just how it works. That's why we have constraints on the State built into the Constitution, and why we need to both understand them and enforce them.
And that's exactly why the State doesn't teach us that.
The camps don't teach anything effectively, but they don't teach some things at all; like the reasons for those very constraints. Reasons which we have consequently abandoned, Progressively, to the extent that we no longer understand them.

To wit:
You cannot possibly internalize the notion of your own sovereignty, without some awareness about the source of that sovereignty.
America was purposefully designed to incorporate the principles of Christianity into a governing framework, by-and-for a Christian society. It was devised to be in all-ways consistent with those principles, and in no-ways contradictory to them.
And, no... as an individual in that society you are not compelled to consider yourself a Christian or to "act like one", other than to follow the secular constraints derived from it just like everybody else.
Many of us seem to think that freedom of religion implies that America is not a Christian nation at all. They don't seem to understand that they only have freedom of religion precisely because America is a Christian nation. Your freedom not to be a Christian is actually one of the Christian principles upon which America was founded. Voluntary participation is a Christian ideal, not uniquely Christian but Christian all the same; which is why being "a Christian" was not built into the framework of the nation.
The ideals of Christianity were, however, built into the framework of the nation. That is what is meant by the assertion that America is a "Christian nation". And the resultant alignment with natural order, regardless of your beliefs about the source of that order, was expected to result in a flourishing society.
And it did.

We've since allowed Christianity to be relegated into a box as just another metaphysical belief system, no different than all the others... a taboo topic in 'enlightened' conversation, and certainly having no place in the Peoples' Classroom.
But, you cannot understand America without understanding the principles of Christianity. That's like trying to learn math without using numbers.
Consequently, we are several generations deep so far in citizens who are supposed to be self-governing, yet they don't understand why or how and pretty-much end up just doing what they're told by anybody with a big enough microphone.
Another consequence is the lack of any coherent body of moral constraints. Rather than growing up with an understanding of the moral underpinnings of our society... in a society that actually reflects those underpinnings, we have increasingly abandoned our own progeny to make their own way, with no moral guidance and in a society that doesn't reflect anything with any real consistency. The result is a scattered herd with no direction and no well-founded, persistent, and internalized constraints on their own behavior.
We've left them with little ability or objective criteria by which to govern themselves, let alone to work together in governing a nation by-the-people.

The solution to this problem is to wrest control of educating our own youth away from the State and return that responsibility to the local community, at the lowest level possible; where effectiveness and accountability are both maximized, and to leave the question of what to teach to the local group of self-governing Americans whose children are being taught there. It's literally nobody else's business.
Teachers and school admin are mostly wonderful people, at least in my experience; but bureaucracy, politicians/public-sector unions, and subversive de facto priorities are literally destroying the best nation on earth. We need to get them off the teachers' backs so they can do the job that their students' parents want them to do. Then the students can go on to become adults with a coherent, well-founded direction and to build a personal sense of purpose around that on their own terms that is supported by, consistent with, and consequently contributes positively to the society around them.

The only alternative to self-governance, is governance by someone else... such as a king, dictator, or politburo. And we have no shortage of wannabes trying to elbow their way into position for that job. That's where we're headed, if we fail to reestablish some measure of understanding, respect, and adherence to our founding principles.
We desperately need to stop pretending that every random 'point of view' that comes drifting in out of Left field is just as valid as the tried and true tenets of the most wildly successful and most free nation that has ever existed on this planet.
If we continue to blindly embrace and incorporate ideas that violate those very tenets, then we'll continue to undermine the integrity of the framework that was built around them, and we'll continue to suffer the consequences of living in a corrupted culture that has no foundation, no direction, and no idea what to do about it.
A culture in decline.

The one thing we still have, to provide a common destination to strive for, is the Constitution.
That original document gave us a collective destination to continuously pursue. It is the reference on the horizon by which we can always tell whether we're on the right track.
And when we're not on track, we need to adjust our direction... not the destination
