Interesting in this context is completely divorced from morally good/bad. Could be any group from any area at any time in history. I’ll start with a few, followers of the cult of pythagoras, contemporary black Hebrew Israelites, antiracist skinheads and the Amish (neo-luddites in general). Don’t be racist or a prick to other people discussing.
Think about how awful covid was, even for a lot of people who didn’t get seriously ill. Now imagine if we knew nothing about where it came from or how to prevent or heal it, and nobody, absolutely nobody could reliably give any insight.
Then it lasts for seven years, nearly halving the population, before coming back seven years after that. In a place where seven is a religiously significant number.
I would have gone fucking nuts too.
