There is a bit of ambiguity to the second amendment
Not any more, there's no ambiguity since SCOTUS ruled that the right to keep and bear arms is unrelated to membership in any militia. It's right there in English if you don't try putting in meaning that isn't there.
Pretty quaint.
However, in a year, the SCOTUS could change their minds. Even now, they are considering a case that effectively ends the SCOTUS. That would be that there is no limit on presidential immunity. As the previous occupant has already stated he would be a dictator on day one, and within his legal teams definition, he has the right to execute anyone he wishes with impunity. Their argument that he would have to be impeached, then prosecuted has a presidential loophole. Just kill anyone that opposes you. You can't have an impeachemnt if anyone that wants to impeach you is killed.
The constitution is written to be interpreted. Under most circumstances, it works out okay. I don't really have a big issue with the present interpretation. But as we have seen, SCOTUS is pretty free to change previous law to suit political parties opposed to it's own previous rulings.
Which of course, in it's present president as dictator hearings, determination, is the equivalent of a democracy taking a democratic vote to end the democracy.
There is a right to keep and bear arms. They clarified and emphasized the meaning for stating this right as explicitly protected, that being there needs to be a population of men trained in arms so that a militia can be raised quickly.
It was never ambiguous, but those opposed to protecting our rights thought to try creating ambiguity by misinterpreting plain English. That worked up to a point, and in the past 30 years or so people have been clawing back these protections. One example is "constitutional carry". https://en.wikipedia.org/wiki/...
But those I have met who are in the unorganized milita want absolutely no constraints. They want anyone at all to walk into any gun store, show, or any gun show car trunk seller and as long as they pay, that's it. No ID needed, no background investigation, You can be an active criminal, or mentally ill, The believe all of those have an unalienable right to buy, possess and use firearms against other US citizens.
I was with you up until the point of "active criminal or mentally ill". People do have the right to buy and possess firearms, there is no right to use them against other US citizens. Assault is a crime. Threatening someone with a deadly weapon is assault. Those lacking sufficient mental faculties to know how to safely handle dangerous items do not have the right to arms. This lack of mental capacity could be due to age, intoxication, injury, or mental illness. But to have any rights removed requires a legal process, evidence must be presented, the person must be able to provide a defense, and so on. The courts ruled on this as well.
Are there those that believe there's some right to use firearms against others? No doubt. Are these in any way seen as credible or a threat? Perhaps. What do you propose we do about it? It appears you would like the government to censor people, disarm them, perhaps even have them locked up without due process. I fear the government imposing such restrictions more than any loony tunes militia.
