@Kaishi It's not that they necessarilly live in a war zone (although gang lands in certain cities are more dangerous than some wars zones I've been in), but it is a safety thing from my perspective as a parent.
Because people do have firearms.
So, as a parent, I needed to make them as exciting as a 2,000 pound battering ram that can go 150mph. Aka, a car. Toddlers will often accidentally start vehicles to disastrous effect, and young children dash into busy streets...but we teach kids, day in and out, what to do and not do with cars. How to behave around them, how to behave when others have them, and later how to use them as safely as possible.
Most of the shootings in this country are accidental. A huge number of those shootings are kids playing around. Either out of ignorance, or a combo of sneaking+ignorance. They're never taught proper weapons handling. They aren't allowed to handle them so they use them in secret. It's not farm kids who use rifles for hunting and scaring off coyotes & bears & big cats & gators that are shooting themselves. It's (usually city) kids sneaking into mommy or daddy's gun locker and getting them out to play with in secret, or show their friends (just like porn and other taboo items). The only experience they have, and only rules they know are from TV & video games.
My son has been in 2 incidents with firearms outside of my control that I know of. His stepfamily was spinning .22s around their fingers like cowboys (f*cking idiots!!!) and he went 4 walls away and sat behind a book case when they wouldn't stop when he asked them (also wouldn't clear them for him, assholes!). And a friend took him to see his dad's pistol in secret. He's 12. I've been teaching him what to do in these situations, but it's still partially just luck no one was injured (especially as one of the .22s did discharge). The other part is that he knows "Always treat every weapon as if it were loaded, keep your finger straight and off the trigger until you are prepared to fire, never point your weapon at anything you do not intend to shoot, always know what's behind your target."... As well as "If you wanna go shooting? Just ask. We'll head out to the range. Nothing taboo or 'wanna touch it???' About it.
I can't keep my son safe, but I can teach him how to protect himself. With firearms, in is country, it's not about using them to protect himself. It's about protecting him from them. Counter ignorance with knowledge. Counter exciting with normal. Until breaking weapons handling rules sounds about as "fun" as running into traffic. Only something an idiot or a baby does.
