Goneriding, this isn't a rolkur debate. But a peta debate. Rolkur has been done to death.
I find it interesting, and quite a smrt move by peta, that they have targeted arguably one of the most famous horse/rider/owner combinations in the world, or at least the most covered in the media. By targetting such a big name in the sport, IF this charge against them comes to heads, it's going to send a ripple through the rolkur/LDR community.
As for the confinement, I do agree on a level with peta (can't believe I put agree and peta in the same sentence just then!), I'm a firm believer in horses have time in a paddock. If Carl Hester can put Blueberry and Uti in a 'field' during the day, surely others can follow suit. I know I know, risk of injury and what not, but you can make a small, and very safe/secure paddock for an hour or two of fresh air for the horse.
I know that it's very much culture to keep these horses locked up, but honestly, if I couldn't keep my horses anywhere that allowed them time in a paddock, I wouldn't have horses.
So yes, I can side a little more closely with PETA on that front. Just an hour a day of letting a horse be a horse would be lovely.
