Supporters of animal rights believe that animals have an inherent worth—a value completely separate from their usefulness to humans. We believe that every creature with a will to live has a right to live free from pain and suffering. Animal rights is not just a philosophy—it is a social movement that challenges society’s traditional view that all nonhuman animals exist solely for human use. As PETA founder Ingrid Newkirk has said, “When it comes to pain, love, joy, loneliness, and fear, a rat is a pig is a dog is a boy. Each one values his or her life and fights the knife.”
Only prejudice allows us to deny others the rights that we expect to have for ourselves. Whether it’s based on race, gender, sexual orientation, or species, prejudice is morally unacceptable. If you wouldn’t eat a dog, why eat a pig? Dogs and pigs have the same capacity to feel pain, but it is prejudice based on species that allows us to think of one animal as a companion and the other as dinner.
