It’s speciesist to believe that the differences between humans and other animals are enough to warrant torturing and killing those we don’t relate to. It’s speciesist to think that we are superior and are therefore somehow justified in raping, caging, and mutilating animals who don’t look exactly like us. It’s speciesist to exploit others because we don’t understand them fully or at all, to assume that they’re not as intelligent as we are when we measure their intelligence in human terms, and to dismiss their suffering because it benefits us.
