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.
I’ve read about these guys. Their take on it is that the skins started as a working class solidarity movement (the short hair is for safety while working on factory machinery) that got corrupted by nationalism and they have more in common with immigrant workers than with their own country’s capitalists.
