Gary L. Francione said this quote
“ 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. ”
