" Lilath took me to a slaughterhouse on Earth when I was young. And I saw how they would kill the cows and then make them into food for us to eat. Tell me: why are cows different from people? Cows have dreams. Cows have affection for their friends and family. If you are going to say it is because cows are less intelligent than people, it is acceptable to slaughter them, why is not acceptable for me to slaughter people who are proportionately less intelligent to me than cows are to them? And if you say it is because people feel more, then I invite you to stab a cow and a human in the throat and see how very similar they are. "
