The "infamous" blue tongue video is of a horse that got its tongue stuck BETWEEN the two bits....not because of the rider applying so much pressure. While this does happen, it is very rare. The problem came when the rider did not notice this problem and quickly fix it.
People using that video to disgrace dressage really irritate me. Tongues can get between bits, but again, it is very rare.
