Writersoul: I would guess we call it Darchei Ha’emori because they were known for their superstitions. I think I saw that mentioned somewhere but I don’t really remember. It makes sense though.
I just want to clarify. I’m not against all Segulos or Minhagim based on Kabballah. Far from it. There are many Minhagim that we have whose Makor is in Kabballah. Those “Minhagim”, however, without a real Makor in Gemara or Kabballah or that we can clearly see where we borrowed it from the pagans (and this is the absolute best example) are clearly Assur Min Hatorah, no matter how many people picked up on it over the years. (And especially Bizman Hazeh, where everyone in our society loves to borrow Segulos and Chumros from each other, these types of things can spread so easily and quickly and it’s a real problem.)
