These just might be the best, most succinct two paragraphs on the rights protected by the 2A you’ll ever read:
Does everyone who uses a firearm to protect himself survive? Of course not. But as a free man, I do not consider my inalienable rights to be contingent upon my ability to exercise them successfully. I may debate freely, even if I am destined to lose the argument. I may enjoy a jury trial even if I am guilty. And I may defend my life and my liberty even if I eventually succumb.
It is from this understanding that all conversations must proceed. The Second Amendment is not “old”; it is timeless. It is not “unclear”; it is obvious. It is not “embarrassing”; it is fundamental. And, as much as anything else, it is a vital indicator of the correct relationship between the citizen and the state and a reminder of the unbreakable sovereignty of the individual. Unless those calling for greater restrictions learn to acknowledge this at the outset of any public discussion, they will continue to get nowhere in their deliberations.
Anyone who would live free can only hope so–and be fully resolved to do absolutely anything and everything he deems necessary to keep it that way.
