This is just my opinion, but gun advocates seem to me, much like pro-choice advocates.
They oppose any restrictions whatsoever. Even sensible ones.
Believing that if you give the opposition an inch, they will try to take a mile.
And, sadly, I believe they are right.
Face it folks. We, as well as all future generations, are yoked by a constitution written over 200 years ago by men, from a society who mostly possessed, and thought in terms of, single shot, black powder pistols and rifles and the freedom to possess them.
Now, if we could go back in time and tell them about automatic weapons and other advances in the future of weaponry, things might have been different. But we can't and we didn't.
Now, it's way too late. These advanced weapons are here and they are here to stay. And if some whack-job is able to get his hands on one, I want to be able to do the same to protect myself and family from them. Can't put toothpaste back in the tube. All the talk about confiscation, regulation, or whatever, is just wasted breath.
I do wish it had been different. I would gladly forego my passion for deer hunting if it would just save one child. But it's not different. We have to play the cards we are dealt. As long as some punk-ass-gangster has a gun, so will I.
Adapt and improvise.
