Yeah I too think it's stupid to be banned from a relay because of saying "idiot" or "fucking" but if you operate a woke relay, that might be a rule you want to enforce. Ultimately, a nostr relay is just someone elses server and database, which speaks the nostr protocol. You and I don't have any inherent rights to write to someone elses relay, the relay operator is free to implement any filtering/censoring they want to. That just means that you are censored from posting to that relay but you're not censored by nostr . You can still post to other relays or your own, in contrast to getting banned on Twitter where you loose your entire social identity if they don't agree with you.

That said, most people tend to agree on some stuff as you said (such as pedos = bad) so I'd expect most relays to accept most people.
