Embryonic stem cells are also dangerous when used in adult patients. Cancer, growth of hair/bone inside the brain, are just a few of the results from embryonic cell experimentation.
Embryonic stem-cell research is not about finding cures for anything. It is all about establishing the principle of killing some human beings for the benefit of other human beings and ultimately, for purposes of the State, the same principle that has brought us the Progressive enthusiasm for abortion and various sorts of euthanasia. It is a Leftist dream and is part and parcel of the principle of the government being in the business of creating some version of New Soviet Man.
