Would I ever intentionally bang the bit agaisnt a horse's teeth? No, it's unnecessary and wouldn't accomplish anything. However, just because a horse feels slight discomfort from it, it does NOT constitute abuse. Watch a few videos of the recent TWH controversy. Go to a local rescue and watch some of the neglected horses that come in on death's doorstep, or the PMU mares, or the horses forgotten in a deceased neighbor's barn for years, practically standing on their fetlocks because of toes that are curled over. THAT is abuse. Abuse is not hitting a horse's teeth against his bit.
