Maybe I have a decent understanding exactly because I *AM* a teacher? I have a completely different experience than your wife. Not one teacher I know has a carry permit (you generally cannot get those in my area) and nearly none of them have any experience with guns. Trust me... if I tried to discuss going shooting this weekend, there is exactly one teacher I can discuss that with (and she is an unmitigated bad ass... sort of Sarah Conners-like.) And yeah... the majority of teachers I work with are women under 30 or over 55, and would be nervous around firearms. A bit sexist and/or stereotypical? Sure. But also a bit true.
It has nothing to do with teachers, honestly; it has to do with people, period. I don't trust the majority of people to be proficient and trained enough to respond properly in a life or death situation. Maybe I am wrong about that... I suppose I am a pessimist by nature.
And I don't get where you are getting this idea that people aren't proposing anything? There is PLENTY being proposed. Restrictions on gun availability, stricter background checks, mag size limits, extended wait times, limits on ammunition, more aggressive mental health evaluations that are tied to gun access, better funding for mental health services, tighter building security... there is a ton being proposed. Not all of it is feasible, a lot of it is expensive... but damn, we don't seem to be doing anything except literally the most obvious stuff. Banning bump stocks? We can't even get THAT done.
But yeah, adding more guns to the equation, especially in the hands of lightly--trained individuals... most people see that as a net negative, in terms of lives saved vs lives lost, and as someone who is familiar and competent with guns, who spends his life in schools, and spends a lot more time thinking about these things than most people... I agree. We see that in states with less gun control; the states with more gun deaths per capita are the states with less gun regulation. It's a pretty simple equation, even if solving it is NOT simple.
Anyway, whatever, this is really getting "political" even though no politics is being mentioned... we can wait till the off season to discuss; there will be plenty of school shootings then.
