Long read.
Incel, volcel, mgtow, MRA, RoK, gender wars, LMNOP social media herds, bodybuilding bro culture extremism, and on and on and on...all splinters of splinters of splinters that started in one place for teh lulz and got suborned by active measures specialists. There's no bellies being filled by this, there's no endgame in justice or fixing actual problems. All there is is schadenfreude for any number of past injustices and the manipulation of those feels to provoke mischief. The only true purpose is chaos and a nation at war with itself.
People are laughing and thinking it's just some goofballs running around posing, and the scope is much, much wider than that. That's exactly how these people thrive, not being taken seriously.
