Not wanting to eat animals because they're smart (like humans) is speciesist. Why not value ability to smell instead?
Is there a reason that problem solving or self-awareness (other than we have it) is more valuable than appreciating the smell of poop?
Peter Singer has a good test to avoid speciesism (which like sexism or racism is unjust by definition, so wrong, and as wrong ought not to be done).
What we do to animals, do to humans of comparable cognitive abilities.
Would we factory farm, keep in zoos, test products, or hunt toddlers or down syndrome kids?
If no, then shouldn't to non-human animals
If yes, then lets
To avoid speciesism we should either treat animals better or each other much worse.
