The reason originally given was that they "misgendered" them. The chief released a statement saying that he had personally reviewed all recordings and found no evidence of this. Also made a statement that they knocked on Keffals door, and took them into custody without any issues, in direct contradiction to Keffals statement about waking up with an assault rifle in their face from the 'SWATing'.
Worth noting that as part of the police detaining them, they also confiscated their phone and hard-drives. Which might explain why they are 'fleeing' all over the world except to Canada..
It is approaching something like a religious taboo or literal OCD, as if they would be irrevocably damned by reading some bad words. While at the same time pathologizing everything outside their own narrow spectrum of permitted opinions as some kind of "-phobia".
Really everything about this group is contradictory:
* self-professed socialists / communists / anarchists who eagerly support megacorporations
* gloat about how they've basically won already, while justifying their actions with being existentially threatened (didn't Umberto Eco write something about that once?)
* academic background and vocabulary, try to shut down any nuanced discussion
* ironic statements like #killallmen are fine, while even mild criticism of them is proof of genocidal intent
Yes, there are vile comments on KF, and a large number of users do seem to be edgy trolls (the bad kind, i.e. those who go after targets other than cis/white/hetero men, see last point above), if not outright neo-Nazis. That does not mean that the factual information they post isn't accurate.
Deplatforming will radicalize them further, while hiding the problem from view. Conspiracy theory: perhaps that is the actual intent of such actions, to destabilize democracy and prepare it for Russian / Chinese / Western authoritarian takeover?
