The 2A is only one of the several that require vigilant watch. Of the original 10, I do believe the only one not yet violated in one form or another by Congress or the Executive or ruled upon by Black Clad Judicial legal beagle visitors from other planets who seem to have no inkling of the COTUS/BOR's, would be number 3.
Each of the others have been violated due to the stated Wars on Alcohol, Communism, Drugs, Terror, and Crime in general.
Citizens (?) of this fine nation have publically stated they'd rather give up "some" of their rights in order to be safe (whatever that is).
I think all here would rather fight using the ballot. Only problem being, once elected officials who get into office by promising any and everything to 50% +1 to get elected, they tend to listen to the guys with the $$$. Some may fear for THEIR safety due to their actions while others seek to find ways to infringe on ALL or AS MANY of the populace's rights as they are able in order to hold onto their newfound power(s).
But we all know this. Madison knew this. Jefferson, et al... all knew human nature. They knew and saw that only an armed people could live in a free state of being. They judged that to be more important than a "safe" state I reckon (I don't see much language guaranteeing living in a "Safe" nation or state. Life has inherent risks).
Some swear by an oath and live it. To others, they're just meaningless words.
I opine that the 120 million people killed by their own governments in the 20th century wished they'd at least gone down fighting... but alas. They could not.
I reserve that right.
Too bad for those other 120 million. They ended up with neither liberty nor safety. Some smart old white guy with bi-focals might've offered them some advice, if they'd only been willing to listen and retained the tools useful to be able to act upon it. Instead of saying "I'd better obey that new law".
But it's not JUST about the 2A, rather ALL of our rights, enumerated or otherwise. (There's that pesky 9A talking)
But whaddaIknow?
