Suppose you are a devoted and motivated vegetarian on moral grounds. When you are out with your meat-eating friends, you often lecture them about the harms their meat-eating habits are inflicting on innocent animals. Some of your friends proclaim that they agree that the common industrialized treatment of farm animals is abhorable, and that they therefore stay away from meat from large-scale industries and only eat meat from small farmers committed to the proper treatment of their farm animals. They claim that because of this commitment they are doing nothing wrong when they sink their teeth into the prepared flesh of animals. In a desperate attempt to encourage your friends to see the wrongness of their culinary habits, you cite their reluctance to eat meat from dogs, cats, horses and humans. But your meat-eating friends remain unconvinced.
