Hmm, I don't recall painting an entire discipline with a broad paintbrush, just pointing out that he refused to train any more WP horses when the peanut rollers (which were often trained with jab and yank...among other things) became popular.
I prefaced that blog post with the statement that I am not a WP trainer, nor do I wish to be, but I do train free-moving, level-headed, effective horses that actually have a purpose outside of an arena. Would they be in the ribbons at a high level breed show? Nope, but that doesn't make them a lesser quality horse with lesser quality training, just different.
Your method probably works too, I may try it someday, but don't tell me mine doesn't work because you haven't ridden one of my horses, so you don't know how they travel or handle. My customers are happy and so are my horses, so that's all that really matters to me.
Oh, and just because todays WP horses are different doesn't necessarily make them better, by any means. I actually preferred the older styles of horses that were cadenced and controlled without actually looking like zombies...but that's another debate for another day.
