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.
remember the scientist who discovered lyme, was stalked, harrassed and had death threats against him, he had to get private security. he was also saying theres no such thing as CHRONIC lyme. its basically a cult with an industry behind it. like someone said it likely it some other disorder, like CF or a mental component. if you dont live in lyme “country”, or unless you were near there but dint see a tick or anything, ubt a telltales bullseye rash.
