Wow, it made me mad to listen to that dude on the video that thought he was so cool. But i really admire the dressage riders for not getting mad. Sorta like when the British made up the song "Yankee Doodle" to make fun of the Yankee's during the Revolutionary War. Instead of getting mad, the American's made it their "theme song" during the War. Good for those dressage riders!!!
I agree with SmartPac....make him swallow his own pill. Afterall, any rider (wether English, Western or other) knows riding is a lot harder than just sitting pretty on the back of a 4-legged animal.
