"I do not oppose violence simply because it is counterproductive. I oppose it because it betrays animal rights philosophy. Those who resort to such tactics really have not understood that animal rights is about the extension of moral concern to all sentient beings--humans obviously included."

Veganism is about nonviolence. It is about not engaging in harm to other sentient beings; to oneself; and to the environment upon which all beings depend for life. In my view, the animal rights movement is, at its core, a movement about ending violence to all sentient beings. It is a movement that seeks fundamental justice for all. It is an emerging peace movement that does not stop at the arbitrary line that separates humans from nonhumans.
