The animal rights movement has been a full-blown movement towards fascism for quite a while now. They use the same tactics as the common bullies so many of us knew and despised in school. It is better to remember them as human trash than to think of them as some kind of overwhelming moral agency. Not that there's a lot of difference between a batch of trash and a moral agency.
America, Australia, England, and other civilized nations have had many opportunities to exercise some intelligence and render this fascist movement harmless. I suggest that while most of us humans have not yet been neutered we find something inside of ourselves to use to defend our lives. When the same person who used to give wedgies and swirlies now wears a uniform and gets his jollies by abusing that uniform, we've got to do something.
