Over at First Things I have a piece describing how utilitarian bioethics and animal rights are working as a pincer to destroy human exceptionalism. They are doing this by, on one hand, trying to elevate some animals (later, others) to legal personhood (animal rights), while on the other working to depersonalize some humans(bioethics.). From, “The Personhood Pincer:”
Unlikely as it may seem, utilitarian bioethics is the counterpart to animal rights in the war on human exceptionalism. Rather than seeking to elevate some animals to the level of humans, utilitarian bioethics advocates would reduce some humans to the status of animals-with the concept of “person” again serving as the point of the spear.
