The essence of the second amendment is the right to rebel against the feds, for this the Americans kept weapons and the feds did not become impudent, because they knew that they would be rebuffed.
However, the left used this to create chaos. Decoupling gun ownership from military training will create havoc and lead to them pushing a gun ban law. That is what they are striving for.
Gun owners must be trained by the state militia, and must be ready to rebel against the feds. At the same time, there is no need to cancel personal rights to protection from villains, but there must be order.
No, the second amendment was not put in place so you could commit treason. But go ahead and see how that works out for you. Might be one of the dumbest arguments ever advanced. There are already state militias. Get a clue.
