Unsoftly pulling on the reins? Yes. Hard hands? Yes. Uneccessary pulling? Yes. Yanking? NO
Is the horse's mouth bloody? Is his tongue cut up? Is he developing sores? I swear to god if any of you say yes I will throw my hands up on this thread since none of you have actually seen inside that horse's mouth. Yanking would be actual drastic damage. When I get home I will find a video of a horse ACTUALLY being yanked on so you can compare.
