That's the basic reason wed have so many breeds to choose from. Somewhere along the line somebody liked something and disliked something else and bred to create what they wanted.
I both agree and disagree with this statement. I think most breeds came about for a purpose, and only now are people really getting into creating "fad" breeds, just for characteristics they decide they like. Orginally the thoroughbred was bred specifically for speed, the qh for ranch work, the percheron for pulling, etc. the friesian was bred as a flashy carraige horse, and is well suited to that. They needed a horse that could pull, and look great doing it. Only now have people said "friesians are purdy, lets turn them into saddle horses!"
I don't like people who are close minded about things, but we are all alowed our preferences. For example, I don't like Quarter horses. Shocking, I know. I have been bitten, run over, and bucked off more qh's than any other breed, hands down. I have seen many halter bred horses with no mind, and several that were bred to work but excelled as broncs. The craziest horse I've ever had the misfortune of working with was a qh. That said, I know there are good ones, and I ended up, against my better judgment, with a filly that's appy on the top and aqha on the bottom. She has the best mind I've ever seen on a two year old. I love arabs, and have no issues(minus the dislike of their suicidal tendencies) with thoroughbreds.
I have no problems with having opinions, as long as people arn't purposefully ignorant about reality (example "Every paint is a wonderful saddle horse!").
