What I actually DID say is that allowing mods admins to defederate entire communities is stupid. If you want to talk about THAT, fine.
I think you’re really misunderstanding a lot about the fediverse if you think everyone must federate with everyone. Choosing who you federate with is a fundamental part of the design. It means communities can choose their own ways to operate, and we don’t have to apply universal rules to everyone.
If a bunch of nazis want to run a server and post racist shit all day we can’t stop them. But we can (and should) defederate from them. They can have their own private island. If someone wants to run a “safe” server for (e.g) LGBTQI+ and defederate from some of the big instances, they should be able to do it.
If you want to be in a community that allows almost everything except racism, and other horrible shit, and federates with almost all servers then there are plenty of servers that support that. You are free to choose that. That freedom to choose is a massive feature (not flaw) of the fediverse.
You can argue it should be user-level, and again that’s something you can choose. But there will be servers almost everyone wants to defederate from, and don’t want to leave it up to user-level blocking because new users will see horrible shit as soon as they log on for the first time.
