"No, animals are not people. But people are animals, and we have many things in common. There is no reason to suspect that it is any less painful for a horse to be whacked in the mouth and aggressively spurred than it would be for a human or another mammal. Horses may not be wonderful at planning ahead and understanding abstract thought, but they feel pain and fear like we do, and they suffer when abused."
And that is why I am personally responsible, you are personally responsible and every other horse person is personally responsible.
