Rationalist communities were fun when they were more about exploring ideas from different angles and less about identifying as a group with superior thoughts and beliefs.
It’s ironic that rationalists spend so much energy criticizing people who won’t tolerate the out group, while simultaneously being intolerant of what they define as the out group.
New communities will appear. Perhaps not ones as international, but that's okay; smaller groups can be better, because they're less vulnerable to evaporative cooling of beliefs; the group just disbands when people start leaving.
When groups get into happy death spirals, it's often easier to just start a new one.
