so, thinking about Speciesism, and i think it's very easily self-defeated. I usually don't take such a strong position right away on issues, but i'm not seeing any logic behind it.

they complain that humans shouldn't kill/eat/abuse animals because it's being predujice based on species.

so why not stop lions from killing gazelles? Why is it ok for animals to eat other animals?

I certainly don't think that lions will learn by our example. It's nature. And to think that we, as a species, should not eat other animals because we have the mind to think that it is wrong, is speciesism itself.
