I agree with what Ex-SD said, I grew up in the same way. I got a shotgun for Christmas at 11 and my Mother bought me a 22 for my birthday when I was 13. Along with all the hand me down hunting rifles I had quite a collection that I kept in a gun cabinet in my room. My family has been into hunting and shooting since forever and gun safety is second nature. Growing up my family would have never tolerated foul play with firearms and I never once thought about settling a dispute with a gun.
I think it really boils down to upbringing and the reality of what guns really are, responsibility. I started hunting at a young age so I knew that once you pull the trigger theres no taking it back you only shoot at what you intend to kill. Kids that don’t have this type of firearm education probably don’t respect guns in this way and shouldn’t own them, this applies to adults as well. Its just responsibility, like not storing gasoline next to the gas water heater, its just dumb and could get you killed.
