I think it should just be taught in high schools. No political BS beyond "don't go making SBRs," no indoctrination either way. Just plain old gun safety and operation.
Sorry, no, I don't see that happening again in US schools, without another "fundamental change" in America.
The "progressives" (by what ever name they call themselves) have spent the last century working against it, and have been very successful in the last half a century or so, and absolutely dominant in the past few decades.
There was a time when schools allowed Hunter Safety classes to use school rooms and property. There was a time when high schools had their own (smallbore) rifle teams!
There was a time when there were many open air shooting galleries in NYC!! (this is where the "gallery" pump .22 short rifles became so prominent. And, no, they weren't chained down, and yes, they did use real, live ammo!!
And even if you could get them to do it, today, there is no way you will get around at least some people adding in their political dogma.
The only thing schools seem to want to teach about guns, today, is that they are BAD, evil things that everyone would be better off without.
(except, of course for the police, and Mummy & Daddums personal private paid security guards....
I am of two minds about teaching gun safety in schools, today, assuming you actually could. First is the pro side, reducing dangerous & fatal accidents.
The Con side of that coin however also applies, and I am a bit leery of teaching the amoral thugs & punks turned out by some of our schools, how to properly handle a firearm and how to shoot well. They already do enough damage in their generally ignorant state.
