As someone who is weird, the reason I think these communities exist is because a lot of us are on the spectrum and it's honestly so exhausting trying to discuss ideas with people to just be called weird or toxic or whatever else. In a way the reason people see us as a group is because we can't do the groupthink thing, and so it's nice to talk to others who are not going mock you for liking Harry Potter and being interested in AI risk.

As a "group" we disagree on almost everything... It's why we talk to each other.
