The part of twitter that believes the real Jews are of African descent would be a good example no? Antisemitism seems one of the few conspiracy theory topics that is prevalent on both sides of the political spectrum, though on the left it seems to mostly come from NOI types or Muslims who take antizionism a little too far.
BLM UK got in a lot of trouble for saying that discussion of antisemitism was being stifled in British politics, and it looks like they still have their twitter account. Nick Cannon looks like he still has his twitter account as well, though his comments were made on air iirc.
> I've largely stopped using twitter due to the incessant politics, pretty much what you described above but just in a different flavor
I'm not saying there aren't crazy takes in many corners of Twitter, but OP made a very far reaching claim here that I can't imagine holding water from my experience. The examples you bring up seem pretty fringe at best and not representative of common activity on Twitter.
