Whats wrong with animal rights

This reading was very confusing. I didn't understand the argument. Was it that he was for animal rights or against it. For example, when he talked about the humane society I still didn't understand if he was against it or not. I thought the humane society was a good thing, but purposed that they were bad and that they killed dogs. Which in some cases they do to stop the animal from suffering and in case the dog is to blood thirsty. Over all the writing was good but very hard to follow.
