What do you think of people who prefer animals over humans?

I understand why many of them feel the way they do, because animals aren't rational beings and so they won't consciously try to trick you or hurt you or take advantage of you, but at the same time, you can't form a bond with an animal the same way you can with a human, and I think those people have been hurt or witnessed others being hurt too many times, and they need to come to the realization that human contact is something that is priceless.
