"Just as we reject racism, sexism, ageism, and heterosexism, we reject speciesism. The species of a sentient being is no more reason to deny the protection of this basic right than race, sex, age, or sexual orientation is a reason to deny membership in the human moral community to other humans."

"Veganism is an act of nonviolent defiance. It is our statement that we reject the notion that animals are things and that we regard sentient nonhumans as moral persons with the fundamental moral right not to be treated as the property or resources of humans."
