She might, yes.
I think the main problem isn't Rollkur in itself. I think, as I stated, and jaydee also, it's the fact that it has to be used in the warm up ring of national championships. Not only a sign of lack of training, but it also gives an excuse to all the people without background to use it, use it wrong, and unnecessarily, on their horses, just because Anky " does it all the time".
Any equestrian sport has its tricks and gimmicks, I'm sure. It all comes down to keeping it a secret. Unfortunately.
