Let me clarify because I can tell I implied too much and it just ended up not being communicated. That's on me.
My point is an issue with moderation. The simple fact is toxic behavior is allowed because mods/admins/etc. on forums tend to be too cautious with the ban hammers unless a rule is explicitly violated. If someone is disruptive to the community and constantly starting fights, even if they don't "break a rule on the side bar," the mods at /r/politics needed to just show them the door but never did. I don't know if it's a well meaning but misguided commitment to "Free Speech :TM:" or concern about the optics to the community or whatever, regardless if there is someone in your hen house riling up all the hens every day, it doesn't matter if they're a wolf or a hen. Kick them out.
At present I have not seen many admins with the stomach to enforce like that. But if we want to actually not be reddit all over again, that's what it will take. Beehaw I think has some decent ideas about how to handle this problem via defederation, and I think it's a real solution that needs to be explored more, but ultimately admins need to just kick people out when they're particularly toxic and disruptive.
The reason I mentioned the "stop the steal" crowd in particular is because 100% of the time it is just a horrible flame war the moment they pop in. Dozens of removed comments and just insults hurled everywhere.
