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.
Honestly that doesn’t seem that weird. People hanging out and having a good time together with the use of drugs?
Wall Street finance bros do the same thing and I find that way more problematic
