The way their horses are used in ceremonies really isn't good. I don't expect everyone to get it, lots of people who don't know about horses just see it and think oh look how lovely, lots of riders don't see the issue. I don't find it comfortable watching horses some just under their threshold and a few over it.
I've had horses for years mostly rescues, I don't subscribe to the BHS way of thinking so I'm already labelled as 'odd' I find this sort of treatment of animals sad.
