Yes, teach gun safety and safe gun handling to teens at public schools but bar such training at charter or private schools. Also teach revolutionary politics, survival skills, wilderness and urban fieldcraft and guerrilla tactics to the lads and lasses in public schools. Then let the Second American Revolution begin!
Tongue in cheek of course, but that is why local, state and federal governments will likely never support such initiatives universally.
In all seriousness, I think teaching future American adults about responsible gun ownership, gun safety, safe gun storage and the rights and obligations of gun ownership would be very valuable in an over-armed society like modern-day America. I would also advise raising the age that anyone can own or possess a gun to twenty-one years of age unless they take and pass such courses, in which case lower ages of qualification can be had by would-be gun owners.
Cheers and be well.
