You cannot reason only attack the person. Indeed you never answered the question; “do you want every psychotic, drunk and 13 year old youth carrying weapons? Fanatics never answer questions as it upsets their preconceptions.
I did answer the two questions you posed. Then you added ‘13 Year old”. Kids should have guns under adult supervision. Both my offspring got their first gun at 10 YO. Guess what they haven’t killed anyone over 20 years later AND it is highly unlikely they will be killed by an armed person with bad intentions.
