You were appropriately mesmerized by Taylor's work and her ability to discuss it in lay terms without simplifying. However, if she were responding directly, I am sure she would take issue with your idea that stem cells are obtained for research by 'harvesting embryos for the express purpose of their stem cells." When stem cells from embryos are used in research, the "donor" embryos were created by couples (and their physicians) for later implantation in the woman's womb, but because several are created for every one implanted, the unused embryos are destroyed and wasted UNLESS they are used as a supply of new stem cells. The choices are not life or no life, but rather usefulness or garbage.
