@SWP's back made the point that US citizens aren't allowed to keep tank's that fire rounds... or grenades, or artillery, or armed planes, or warships, or missile systems, or torpedo/missile submarines, or NCB weapons... so if none of those are allowed under the wording of 2A's 'right to bear arms', then 2A's 'right to bear arms' is very selective and has been subjectively changed to literally mean 'pistols and rifles (and anything below - bow and arrows, blades etc).
Which makes no sense. The continuing existense of 2A is only acknowledging that it was fine and fit for purpose when it was drafted, but weapons have progressed, and each progression hasn't been allowed to be used by a 'the well regulated militia'... leaving 2A nonsensical - you can't bear any of the arms that have been developed since 2A came into existence.
So 2A is illogical, unenforced/trampled on - because the militia isn't allowed by other laws to have any other types of weapons.
If it is neccesary to have a 'well regulated militia being necessary to the security of a free State', then they aren't going to be doing a hill of beans against anyone with weapons bigger than rifles. So 2A falls down yet again, by not being fit for purpose - the militia can't defend the security of a free state with the weapons they have.
If 2A advocates campaigned (and got) for the general sale of , and free use of all weapons, then 2A makes sense. They'd have access to all weapons, and could defend the state against all-comers. But they don't. They just talk about "their guns", effectively advocating for limiting the "freedom" they generally proclaim.
2A is just not viable or logical (at any interpretation), for either those who advocate it (but miss the nuances), or those who want it repealed.
But as (almost)
@ChicagoBlue says, it's just pissing in the wind, and is just another US hill to choose to die on, despite it making no sense in humanity terms.
