These last two mass shootings seem to be all about intolerance of some kind. And an inability not to act on it... I understand impulsive behaviors, my life has been plagued with things I probably shouldn't have said, or done. But, try as I might, I'll never understand what it would take (short of being in fear for my life) to act on deadly violence.
I think everyone must experience some intolerance to a degree. I do. I'll feel something, then think about it, maybe get a little angry, let it rent a little space in my head, etc... But, usually what I come up with is that I'm just not willing to waste any more energy on it.
But to plan/plot, write a manifesto, drive 70 miles, shoot the place up? Chicken out of getting shot, get arrested, go on trial, probably get the death penalty... I just don't get it. I sure hope there are grants dedicated to studying these brains while they are alive and after they are dead. There is no way that someone with the capacity for that much hate and violence isn't going to show something in the way of cognitive or neurological changes, over time.
I get that hate is an emotion and perhaps some feel it is a soul sickness, I'm not inclined to disagree. I just feel that it must be cultivated to be allowed to grow to the degree it would take to overcome certain self-preserving reactions. And that should show some sort of cognitive changes.
