I remember a conversation I had with a guy in an airport who was pushing support for nuclear energy. I tried to make the case we needed to use less energy... Saying that was needed to protect "all the other animals." He responded, asking what I meant by "other animals." I responded by saying "all the non-human animals." He was absolutely incredulous, saying something like, "I don't know about you, but I am not an animal." I smugly responded by asking, "Oh really. Well then, which are you, a vegetable or mineral?"
