I think - based on the problems I'm having with certain dog trainers (club instructors), that it has to do with "saving face" and never having to learn something new if it means what you thought was right all along - was actually wrong and damaging. I swear - if they'd be persecuting Gallileo for suggesting the Earth might not be flat and the sun does not revolve around the Earth...some weird psychological boost to the ego?
So frustrating. And some of them are otherwise nice people sort of. They're killing my dog club.
