I'm sorry but if Anne Kursinski told me that I was weak or my horse is weak maliciously I would look at her square in the face and call her a B**CH and she was a bad clinician in my eyes. As I would be leaving the arena I would ask for my money back.
There's a differece between critiquing and insulting! People like that give equestrians a bad "snoody" rep.
Sorry for the rant. :o)
