When asked for a justification for eating animals people frequently say that we [humans] are superior to them. But how does it follow that you should eat something just because you are superior to it?
Law abiding citizens might think they are superior to violent criminals. But does that mean that during their lunch hour they should go down to the prison and bite a few chunks out of the local inmates?
Nietzsche believed himself to be superior to the brainwashed Christian masses; but as far as we know he never dined on their flesh in some morbid ritual or any other circumstance.
Where does it all end? If you think you are superior to cannibals do you need to eat them in order to prove it?
here's how joan dunayer answers the superiority issue:
Even if every nonhuman lacked the capacity for human-like reasoning, nonhumans wouldn't be inferior. Why equate human characteristics with superiority? Because we possess them? In the same self-aggrandizing and otherwise-arbitrary way, a superb singer could say, "I can remember intricate melodies and sing them beautifully. The ability to do that signifies superiority." Then vocally gifted humans, many songbirds, and perhaps other nonhumans such as humpback whales would be at the top of the hierarchy. At the bottom of the hierarchy would be those creatures who have absolutely no singing ability, such as Britney Spears. Because human culture features verbal language and technology, speciesists tend to assess intelligence in terms of these capacities. However, if we define intelligence as evidence-based perception undistorted by bigotry and myth, humans compare unfavorably to other animals. While despising nonhumans as mindless, members of "the rational species" riot over the outcomes of soccer games; smoke, eat, and drink themselves to death; poison the air, water, and soil on which they rely; believe that other religions are false but theirs is true; and pay to see movies starring Arnold Schwarzenegger.
why the need to be/feel "superior", or even use that word, or even think that way... ?
We are all different, whether in race, species or stages of learning, or anything else.
Why create an artificial pyramid where the superior is better than the inferior?
variety and differences are part of life and can't be quantified on an artificial scale created by humans
