"This, this and this are bad so the topic we are discussing doesn't really matter. Just deal with being excluded and demonized" It's disturbing that people excuse this toxic pattern of online disenfranchisement that repeats itself over and over again.
There are tons of social media websites out there that would exclude and demonize me. But I don't visit them, and I don't waste my energy complaining about them. Why would I? It isn't healthy to obsess over people who would exclude and demonize you. It is, in fact, itself a "toxic pattern", as you put it. I don't want to expend my finite mental resources worrying about, I dunno, Truth Social or Stormfront or other such places. It isn't some grand injustice that they exist and exclude different people and points of view, it's just how the decentralized nature of the WWW (and people, generally) works.
