I have been doing the "The Will to Change: Men, Masculinity, and Love" book club at menby@hexbear.net recently which has been my only real interaction with hexbear. The book club has been great so far and if anyone wants to talk about feminism and masculinity should join.
There are a lot of in-group signaling across their own users which mostly shows up with acronyms, specific phrases and calling everyone comrade. This hasn't been that difficult in the book club which is long form text and discussion and everyone is respectful and nice. That being said I have blocked a few communities at hexbear because I have found them annoying and taking over my feed. So like everything here at Lemmy I had curate my own experience
The thing about these experts is that these fields have major physics envy where they use complex math to solve these problems which hides massive incorrect assumptions that break everything. They want to be like physics where math can be used to predict what is happening but politics and economics are not controlled by nature but things made up by humans. They are fundamentally more interconnected and random. With these fields its better to be incorrect like all of your peers than being the lone voice that is correct.
