I’m a leftist that’s cool with guns and was raised around them, and technically, not legally, owned my first gun at 11.
A 13 year old still should not have access to guns anywhere in public without adult supervision. I get hunting, I get protecting the farm, etc. None of those involve taking a gun on public transport though.
And yeah, America bad. If this was even remotely a significant issue anywhere else, we could say otherwise, but it’s not.
