This is honestly a really dark pattern that I feel has trapped a lot of unsure/insecure adolescent men. I had a college roommate who had a lot of trouble talking to people, and constantly watched a lot of self help videos (which is honestly a pretty good indicator of self-improvement). However, he was exposed to a lot of rabid political rhetoric at the same time.
All it took to steer him away was getting him outside and with some nice people, but those who are more withdrawn I think are increasingly being exposed to this kind of content at their most impressionable time. It almost feels manufactured.
