People say stupid shit. When you have a place where anyone can publish anything, you wind up with a lot of people publishing a lot of stuff you don't like.

You don't get to decide what sort of discourse or ideas are getting published. Nobody does. That's just part and parcel. You can block people, ignore people, but networks have their character.

The best network IMO for free speech is nostr. There are no controlled or verified identities, censorship is almost impossible. But it has it's character. The content there is the content there. It's mostly bitcoiners. Go use it stand talk about other things if you don't like that aspect.
