2nd amendment, it is there, it have been ruled on over and over, and it isnt going to change. Some additional screening, without the 'slippery slope effect' may be in order, but lets be honest. You can wring your hands and scream all you want, but it isnt going to repeal the 2nd.
As far as being a gun owner, I have been active with firearms since I was 5. I had my first single shot 22 when I was 7, and was allowed to go out alone with it at 8, BUT we lived in Rural Eastern kentucky where guns are viewed as tools, and are/were treated with ultimate respect. Any horseplay with a gun, would result in an ass whooping that you would still be feeling today.
I honestly remember my brother (a year younger almost to the day) and I going squirrel, rabbit turkey hunting as kids, but we were EXACTLY hunting for the table Meals often consisted of beans/rice and whatever came from the garden, or came from the woods. There was no EBT cards (and even if there was, my family had far too much pride to ever consider it)
I was also an Infantryman for 6 years in the Army, so I have had a lot of experience with some weapons most people have never got a chance at.
Guns do not fascinate me at all, I have them, I practice to stay sharp, I hunt still today (yes, I keep the meat, and never for a trophy) but I see too many idiots running around Wally world with their sidearm on, and if the occasion to draw ever came up, would shit their pants more often than not.
Paddock was insane, but no law/screening would have ever caught that. You want my guns? why? I have more range time than 99.9%of everyone in this country, and know what I am doing with my weapons. If I am carrying, you wont see it, and if I draw it, be sure I will use it, but I am not going to cheese up my pants either.
You find a good way to get those nuts away from the guns, without harming the majority of the ones who do it the right way, i get it. Most Americans would be good with that.
btw, Ogion, as of 2016 36% of homes have a gun.
