Is Obama ignorant regarding embryonic science?

Obama and his medical advisers ignorantly think that new findings in adult stem cell research indicate that destruction of embryonic stem cells is paramount. But, in actuality, adult stem cells should be perpetuated instead. Obama and his advisers should preserve, not destroy embryonic stem cells.In medical advancements, adult stem cells are superior. Embryonic stem cells are far less effective than adult stem cells; yet, Obama maintains that it is practical and ethic to destroy embryonic stem cells, which is erroneous.
