Exactly. Just like the rise of domestic extremism is a consequence of young men being left behind by technological progress and algorithmic echo chambers. Seeing no way for themselves in the world they are easily radicalized on social media. The mentally ill carry out spectacular displays of violence once they are nurtured by these groups. "Cracking down on domestic extremism" is a convenient way to maintain favor with the upper classes who are fearful of the discontent and militant attitudes and supposed actions of these groups (people are claiming membership in movements that have no central authority). It does not address the problem though and actually "cracking down" will only further inflame it. The solution is finding a way to offer these discarded people a way forward, real opportunity where they can see themselves being somebody that matters in their community. Attaching themselves to an extreme ideology is a cheap, last ditch effort to be somebody.
