Yes, this captures the essence of what I'm saying.
I would just add for clarity that I don't think that it's "wrong" for us to elevate life that's more like us, and so I don't think it's "wrong" for animal rights activists to behave in the way that you're describing. I only take issue with justifying that behavior by pointing to specific biological features, when to me, it feels closer to the truth to say that we behave this way because it feels right, and it feels right because of something inherent to the human experience. I believe this is an important distinction because it helps us realize that human experience is context-dependent, and so our sense of morality will be, too. (E.g. one could argue that it's less moral to eat meat now than it was 500 years ago.)
