In the beginning I think the video was correct in saying that we have alot of harmful and unnecisary equipment to control our horses. But is there no middle ground between to much tack, and none at all? You can ride your horse in a snaffle in a pain free way. You can ride your horse with tack and it will still love and respect you.
I think it has a good underlying message but it ony shows abusive riders with tack, making it buyased, not all competition horses are treated that way. IMO it seems to be saying if you use tack your heartless.
