Just in case anyone in your life starts in with "That's because schoolchildren are in so-called 'gun-free zones'!" -- so are servicemembers, for the most part. Servicemembers don't walk around with their firearms. They are issued to them only when needed, and taken back immediately after, and ammunition is transported separately and issued at the exact moment it is needed, and taken back immediately after. And if a servicemember's commander wants to suspend their access to that weapon for any reason whatsoever, that commander can do that. I have done this myself.
If they want to compare schoolchildren and servicemembers, then let's do that. Let's hold the entire country to the same standards of vetting, training, accounting, and issuing weapons that we hold the military to.
I fucking dare us to do that.
