This is a good piece on how kids get sucked into the alt-right vortex, although I think there was maybe a bit much of an attempt to blame the kid’s trauma on an overzealous idiot of a school administrator. People join the alt-right without ever being unfairly accused of sexual harassment.
The parents’ approach was just right, in my opinion: dealing with it patiently, giving their side openly, letting the kid wrestle with it himself with only gentle guidance. I remember when my son asked for a book by Thomas Sowell for Christmas — I was anguished, heart-broken, wondering where we went wrong, looking through the yellow pages for deprogrammers, anything to break the chains of libertarian conservative propaganda. But we got him the damn book anyway, and we’d still love him even if he’d asked for Ayn Rand. Fortunately, he seems to have turned out OK now.
