This talking point is a deliberate strategy of the far-right that has no basis in reality.

The far-right is growing because people like him are allowed platforms to groom people for extremism. And whenever that platform is at risk, they start trying to guilt people by bleating about "censorship" and "free speech" and "echo chambers".

Just ban him. He will never contribute anything of value. We're already aware what the opinions of assholes are, we don't need reminding.
