I'm going to state what I stated in another forum....
Horses are not deer. They are not built to jump like deer. PERIOD. Making horses jump huge heights is cruel because it destroys their joints. I think that steeplechasing is cruel. Show jumping is not very nice either. I think that horse racing is cruel (when you race babies and throw them away when their 4)
I think that most rodeo events are cruel. Bucking horses and wild horse races are a cruel joke. People on good ranches NEVER treat their animals that way. I've worked on several.
Horse abuse is cruel, and there's nothing that you can do to stop it entirely. It's sad, but it's true.
