I agree with everyone about the horse needing humane treatment, people who understand and are qualified to ride and care properly for horses, and correct training.
And this is not to argue, or say this is OK with my beliefs, it is just a statement. Arabians came from that part of the world, were ridden and used in ways that we would consider inhumane and yet these were the people who developed the breed, used the horses in these ways, and continue to have and use these horses. The people who are handling the horse and riding the horse are most likely quite used to horses with this temperament, and this is just the way they handle them because they don't know anything different. I've seen quite a few videos online made by people in the middle east riding Arabs and they often are prancing around, quite uncomfortable, the bit is held in a vice grip and you'd swear the rider was going to fall off.
When I was in Iceland, I visited a museum. We know the little Icelandic horses are extremely tough, hardy and have temperaments that will put up with almost anything. I was appalled to see the old historical photographs that showed how these horses were developed to be this way. They were used so harshly and made to do such things that only the toughest horses with the most steady temperaments would have made it through. They piled their backs high with heavy items, strapped them together and made them toil through the ice and snow on very little food. As they said, "Iceland was built on the back of a horse."
Arabians are also a very tough breed, and I suspect both their hardiness and temperaments were shaped by the whims of the people who bred them in the middle east.
