I've found said assholes have an attitude that they are entitled to platforms and it's incumbent on everyone else to go out of their way to avoid them. Farcical, but they will scream and cry when the idea is challenged.
I've found these platforms are fine with assholes, they just pick and choose whos assholes are acceptable based on political preference..
Why not put these accounts into shadow ban mode? Allow them to post to their hearts desire, but just have the algorithm never display their posts to anyone. They get to feel that sweet endorphine release from posting their minds, just the rest of us don't ever have to see it.
