But haven't I also disarmed the guy who bought his gun on a lark at a gun show at the fairgrounds, has no idea how to really use it, hasn't had any instruction, and keeps it in the glovebox because he thinks it's cool?
Honestly -- if every gun owner was like you and knew how and when to use their weapon and didn't decide to carry just because it's fun to have a gun, I'd have no issue with everyone walking around armed. If everyone who wanted to buy a gun had to pass a test, like we all have to do to drive, I'd be a-okay with it all. But that's not how it works.
So if posting "No Guns Please" at my business stops even one person from bringing his gun inside where he might discharge it by accident, then I'm good with that.
I've lived on my own for over 40 years and have never felt the need to be armed. When I see someone write,
"You are scared if I have one, I am scared to not have one.", I always wonder where it is you live and what it is you're scared of. In all my time on this planet, I've never once been in a situation where I thought, "Man ... if I only had a gun right now." Maybe that makes me naive or just really lucky, I don't know.
I have, however, been in two situations where very nervous gun owners pulled their guns to thwart perceived threats (a noise in an alley; a stranger on a street). In one case, they fired -- wildly -- and thankfully only managed to ding a dumpster. They pulled the gun and shot before even saying anything. I looked at him and said, "What the hell was that?!" and he said that he was nervous and "it just happened."
In the other, the "stranger on the street" ended up being an off-duty cop who was walking his dog. THAT was an interesting conversation. And in that case, I had no idea that my friend even owned a gun. When asked about it later, he said, "I wanted to protect myself". He'd never taken any shooting practice, no time on a range, no safety class, nothing.
Those are the people who shouldn't carry guns. But there's no one out there telling them that.
