@Rusty O'Toole and
@MrMatt , let me give you the example of an American man I know, someone who was a friend and colleague, who was radicalized by MAGA/Qanon. Why don't you tell me what society should do with this man.
We worked together for years, in fact he sat at the desk next to me. Nice guy, a smart guy. We went for drinks, talked about our dating experiences. Even back then he was a bit weird, very obsessed with 9/11 conspiracy theories and conspiracy web sites.
I didn't hear much from him over the last 3 years (the Trump years). I started sending him text messages near the election, and I was getting back very crazy responses. He was writing that democrats are child molesters and sent long, rambling text messages about democrat agents who would go around molesting children in China. Virtually every text message I got from him was about pedophilia. I stopped responding. Then he texted me that he's going to "do something to stop the evil forces" (something to that effect).
I debated whether I should report him to the police or FBI since that's the kind of thing lunatics say before carrying out attacks. But since he's my friend, I gave him the benefit of the doubt and didn't tell anyone. I hope that my inaction isn't going to result in people being harmed.
I did show the text to a friend of mine, who remarked, "he's lost his mind. This guy needs help."
This man will never be able to get a job ever again. When he shows up in a workplace and starts talking like that, everyone is going to see he's a nut, and step away from him. He will ONLY find company among other people with his extreme MAGA/Qanon views. He will consume all their media, hang out in their discussion groups. This is very similar to how people enter religious cults or extremist groups in general.
So what does society do about him, and millions of other men like him in America? Do we leave them alone, so they can indulge in their increasingly crazy fantasies? They are trying to murder people.
