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.
since they dont know what they have(so csf is not even on the table for them), they dont seek out 2nd opinions and just attribute all thier symptoms to “chronic lyme”, because its an “LYME DOCTOR” convincing them.
