I've grown up around horses. I've been riding as long as i can remember and i can agree with the statement that a horse has a mind of its own and will do nothing it doesn't want to no matter what you do. theses horses were probably scared the first few times they did it but grew to love it. I highly doubt they were beat until they did dive. People who have never been around horses just need to be quite they just sound like complete idiots to us that have and know about horses. Just because you can read a book doesn't mean your an expert on these animals.
