My reasoning? Because if you "give an inch, they'll take a mile." I'm afraid of the abuse that could come of it.
abuse? from what? there are more than enough embryos from the fertility clinics, so there's *no* demand for embryos. if you make dinner for a friend, are you scared he's going to eat everything in your house?
However, I think Bush's policy is a happy medium. Don't kill anymore, just use what we already have.
it's a stupid medium if you ask me. it leaves the scientists with insufficient stem cells.... so what's the point?! that's like giving cops half a gun.
