There’s always going to be some level of preferring to help your own species over others. It’s more about dismantling the idea that humans are superior and therefore should be able to do whatever they want. “Dominion over the Earth” stuff. It’s more extending moral considerations to animals that you already do to humans. That they deserve food, shelter, happiness, and to not be exploited (specifically by us). If there were aliens or something who treated us like we do animals because they considered themselves supreme intelligent beings, we’d have a greater capacity to understand what’s happening, but it’d still be pretty close to the hellish condition we subject animals to right now and we definitely wouldn’t be okay with it.
