You say embryonic stem cells offer greater possibilites then adult stem cells? How? Theres never been a single study to show any such thing. There have been millions upon millions of dollars pumped into studies for along time and not one single person has come up with anything positive for them. Sometimes things don't work. You don't keep trying to start a car thats outa gas. We know adult stem cells work, so why not pump huge amounts of money into that trying to find cures? The only reason is because its not a viable political platform. Comparing Embryonic stem cells to finding cures for Aids makies no sense. Its apples and oranges. One is a single attempt to find a cure that has yielded nothing while Aids is a disease where they are trying 1000's of things to cure.
