The controversy was that they got the stem cells from fetuses. Now they figured out other ways to get them. A lot of people think it's "playing god" but what's wrong with that? You're playing god more by driving a car and polluting the earth which could lead to a global disaster more than you would be by growing a new chin for an old man - right? Why would a God be mad about helping people? People think that God can't make mistakes, so if someone were born blind it was his devine plan. So to fix that, would be wrong?
It's funny how the same people who are against stem cells are for the war - which isn't playing "god" it's worse. Our president can over-rule "god" and protest abortion, and then order bombs dropped on another country on the same day?
