The woo I find most annoying is belief that "animal communicators" have paranormal psychic skills.
As a horseman, I sometimes read forums for horse owners, and I have gotten myself into trouble multiple times for pointing out that it has yet to be proven that anyone can communicate psychically with an animal (or human). I explain how cold reading is done, and yet people insist that there are people who can do it, and that the broad they paid $50 to and talked long distance with on the telephone really did connect mentally with ol' Dobbin.
I have asked that someone who uses those services please make a recording of a session for me, so that I can point out the cold reading techniques used, but no one cooperates.
Geez, even the websites of the "ACs" are corny!
After seeing yet another horse forum conversation about how amazing animal communicators are, I give up! Trying to carry a torch for the truth there is a waste of time.
