If embryonic stem cells can produce therapies that can't be developed by other means then they should be used.
Someone's religious beliefs shouldn't prevent another person from getting the therapy they need to prolong, enhance or otherwise improve that other person's life.
Neither the Roman Catholic Church nor Pastor Bob's Drive-In Praise the Lord Congregrationist Assembly should have any influence whatsoever on medical research when it comes to the use of embryonic stem cells.
I see. So, if someone opposes embryonic stem cell research and abortion, they're a religious nut.
Cool. Then you, by default, admit that atheists have no morality and do not care about human life. I mean, only religious people do, right?
