Reactionaries are more scared of noncompliant kids than dead ones.
A shooter ultimately fits into their framework of aggrieved, transactional manliness—I get to do this because I was not granted the deference I was taught to expect, because I’m allowed to uncork my anger on people—more than a kid that asks “why?”
In fact…dead kids are pretty useful because they can’t speak up or define themselves. They perfectly moldable into whatever reactionaries need.
