I <think> everyone 'gets it' and we know it can be changed. All I am saying is that it is not going to actually happen in the foreseeable future, at least not to the actual document and Bill of Rights (the Bill of Rights was actually part of the Constitution sent to the states and both were ratified together BTW; our southern states would not ratify the Constitution without the first ten Amendments and that was a wise policy indeed).
A method to add an amendment to our Constitution, and the only one to ever actually be used is: a bill is introduced to both the House of Representatives and the Senate. A 'Super majority' of both houses must vote Yes on each bill. That is 75% or 3/4 of each house. (not bloody likely in your vernacular) Then, the amendment is passed onto each of "the several" states, and they must ratify it again by the 3/4 margin either through the state legislature of a specially convened ratification convention in each state. (not bloody likely.... squared)
In the past, the state ratification process was open- ended regarding time but for quite some time now, they have had an installed time- limit of seven years after which time they vaporize if not ratified. This is what happened to our Equal Rights Amendment.... it could not reach the 38 state ratification requirement and so it just timed out.
There is just no possibility to alter the second Amendment through this process, again at least for the foreseeable future.
I get that it's unlikely but some people need to accept that the mechanism is in place and that it could in theory be changed.
I believe (to summarise) one method is by a constitutional convention called for by two-thirds of the State legislatures" and then that a proposed amendment becomes part of the Constitution as soon as it is ratified by three-fourths of the States (38 of 50 States)
As you say, there's a bit of a sea change at the moment with various states bringing in their own legislation and I'm sure people will be keeping count to see if the number of states starts to approach that critical mass required for a constitutional convention (33 from 49).
