I found this old thread that describes some of the nasty comments GM made over the years (they aren’t all from GM, but many are). https://www.chronofhorse.com/forum/forum/discussion-forums/hunter-jumper/13866-funny-mean-or-combination-quotes-sayings
Putting dirt in the mouth of a rider who yawned during a clinic? Making another rider roll in the dirt? To be honest, he is beginning to sound like a sociopath. Perhaps this whole debacle will trigger some reflection by the h/j community as to how such abusive behavior came to be widely accepted and even admired as the path to riding prowess. It’s like there was some kind of mass delusion going on. (And I don’t mean on this board. By and large people on this forum are such intelligent and independent thinkers, it is really quite impressive).
