You consider humans superior in intellect and ability compared to all other animals yet can't grasp the fact that some humans have chosen to use said superior intellect and ability to avoid killing other animals?
Isn't that usually the argument that anti-vegans use? That we're the top predator due to our intelligence and technology and therefore we have an intrinsic right to the lives of other animals?
That would be an incredibly bad argument. Because it's not a motive, it's just descriptive. "we're at the top so we have the right" it's just a claim we make for ourself without considering how we got there.. and what if a smarter, more advanced alien race would come down to earth and conquer us? Would they agree that since they are top of the chain now they have "the right" to slaughter us? Obviously not. So then we would claim: "we're smart! Look, we know math. And love.. we also feel pain.". So these are important to us.
