Yes - I was trained by an Olympic Show Jumping coach (British 3-day team) who used the exercise, and have done so with several different hunter and jumper trainers since.
I was in a very similar boat as that rider, at about the same age at a clinic with my coach. I think that’s why I feel so strongly about this particular case - I’ve been that rider and I know for a fact I was allowing that horse to squirt left or right. I felt like I “couldn’t” stop him. In reality, I was giving him the exact same ride that rider was, and was being passive when I needed to be an active, stronger, rider.
What I needed from my coach (and got) was yelled at that I was being a weenie (those weren’t the words used but it’s been 30 years since that particular lesson so I don’t recall them exactly) and I needed to stop that horse and mean it. If any horse would have flipped it would have been him, but he didn’t and I managed to halt him straight on the line. I needed to be firmer, and I was being a weenie, tbh.
We all have our own experiences that influence us as to how we view these things. Makes the world a very rich place, but communication very difficult.
I think that’s why I’m less concerned about the words used in this case, and far far more concerned about the actual abuse from Parra. Words can mean many things, but Parra is very clear with his actions.
