There is actually a fair amount of data available online. I didn't choose to say more than I did about that, as it wasn't the focus of my essay. They are mostly under 30, white and Asian, fairly diverse in education and employment. Not organized, no, but an alarming number are becoming White nationalists. Your point about armed maniacs without girlfriends may be relevant.

Yes, it really would be good if more of us reached out to befriend lonely young men and pay attention to the ones who seem unstable. And contribute to community mentoring programs.

But as a writer with an audience of readers on this platform, I try to blog about topics of importance that I happen to know something about. Not to taunt anyone, but to inform. I suspect these lonely losers have been responsible for more shootings than have been attributed to them in the media.
