Now why do they do that?
Eve Tushnet posts excerpts from an AP story which tells us how "leftover" embryos created by invitro fertilization are "discarded" (i.e. killed). According to the story, "the reverence that some clinics gave to the task surprised researchers at the University of Pennsylvania and Rutgers University." To be honest, it surprises me too. But it shouldn't... I think we all have an intuitive recognition that human embryos aren't just blobs of tissue, etc., but are real, living human beings. No matter how much we might consciously believe the opposite, reality has its way of "intruding upon us despite ourselves.
