Many, if not most parents don't want their kids exposed to firearms.
That is only because most of them were never exposed to firearms. When I was a kid, students took their guns to school. They had rifles in the back window gun rack of their PU truck. No one thought a thing about it. There were no school shootings, no serial killings, and no one feared guns because they were commonplace and just another tool.
ITMT, I can name a thousand things already going on in the schools and many or most parents don't want their kids doing or learning! Teaching firearm proficiency teaches safety, respect, discipline and responsibility. The very thing kids need.
Yeah . . . . tell me again, what do all of the addle-brained, limp-wristed, fear-wracked, pants-shitting parents not want again? Since when did they ever have a voice in what schools teach?
I bet they don't want to pay school taxes either -- -- -- -- but they pay them.
