I found this at
Wu Wei Verlag's website, a German publisher specializing in, among other things, publications critical of our culture's increasing violence and abusiveness in the field of equitation, which especially the "Rollkur" *) - which means forcing the horse to bend his neck to a point where his nose almost touches his chest, an unnatural position and extremely damaging especially to the horse's upper vertebrae (though in a broader sense damaging to his entire body and soul) - is an expression of.

The text says: "Are you riding yet, or are you still rolling?" It reminded me of what one of my trainers used to say, that the motto of dressage competitions should be "Look what I'm NOT able of!"
Any parallels to the mh system? Well, if you ask me, the whole mh system is an expression of what its professionals are NOT able of, and one could ask them: "Are you helping people yet, or are you still oppressing them?"
