I appreciate your perspective on this. What you describe is about more than just 'assholes don't get guns', although that is a crucial aspect. The way your family owns just 'a' gun, trained for a long while before shooting, respect for following gun laws. This is the opposite of the usual experience around guns in the US. We as a culture in the US are careless and wanton with guns in general from what I've seen.

I was shown how to use a gun when I was 6 years old, my parents were responsible though so it was only an air pistol, but heavy duty, not airsoft. We had a shotgun, 9mm pistol and a .22 rifle in the house never locked up, didn't even have a safe to lock them if my dad wanted to, and the shotgun was often stored loaded. When people here get together to shoot, it's not odd to hand a loaded gun to someone that has never been to a range or even seen one fired before. Plenty of people are much safer than this, but I would guess my experience is the more common from what I've seen.

From what I can tell, most gun safety training in the US is a single sentence: Always treat it like it's loaded, and keep your finger off the trigger until you are ready to shoot.
