I had my own gun and access to guns as a 13 year old. Hunting, target practice, etc. It’s not an insane age to have firearms.
That said, I was raised to respect the fuck out of the danger inherent in a gun, and I used mine to kill deer for food, not kill people I had a mild disagreement with.
Edit: Well fuck me for being born into a different environment ig. Mass downvoting someone for offering a different perspective is healthy for an online community /s
