If animals believed in god, the devil would look like a human being. Animal liberation is a global social justice movement to resist the genocide of the gentle. Like any other social justice movement in history, where an oppressed group struggles for justice, activists are mocked and demeaned. Non-human animals are legal chattel property, they are an oppressed class. Yet they know the injustice of a slaughterhouse. They run and fly from the sound of guns, bite their legs off to escape from traps and chains, gasp to escape the nets and hooks. They go mad in laboratories. 

Art depicting animals is trivialised, because animals are considered trivial. Animals belong to themselves, they are not human property in any world that values morality. All they own are their bodies, which are violently stolen from them. Humans breed animals, only to murder them. There are very few places on planet earth where humans need to kill animals to survive, and nowhere safe for animals to live out their lives in peace. (Sue Coe)
