The article goes in a direction I like: plurality and to allow different communities to develop alongside each other is great. However, I still think we should push for establishing universal human rights. I'm not a fan of moral realitivism. I think every community should be able to get onto the Fediverse, but we don't need to applaud every community to do so, and can also take actions against communities that do bad things (e.g. by defederating).

I would recommend "The Dawn of Everything" by David Graber and David Wengrow, which shows how humans managed to live in different forms of community already throughout history. Maybe in the Fediverse, this could become more easy on the internet, too.
