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 been using WU for probably 15 years. It’s been one of the most consistent weather sites and apps as far as decent quantity and quality of data. I had completely forgotten about the terrorist group with the same name. Now I’ll never be able to unsee it.
