Bob, I saw Joao's intelligent comments and yours, you still have not answered my questions about in vitro clinics and birth control pills and devices. I think the in vitro clinic issue is really important because those embryos, unlike SCNT are the result of fertilization. You know that it often takes more than just one to produce a live birth. So, embryos are being produced and destroyed so that infertile couples can reproduce. Is that OK? If not, what is going to be done with all those extra embryos? Why is this being ignored? AND STILL GOING ON? It seems to me that opponents of both kinds of stem cell research need to deal with this question and they are not doing it.
