^ Thanks for posting that up!

Very informative.
This one passage in the article caught my eye,
But my opponent's accusations nagged at me. ... If I am opposed to abortion for religious reasons but seek to pass a law banning the practice, I cannot simply point to the teachings of my church. I have to explain why abortion violates some principle that is accessible to people of all faiths, including those with no faith at all.
I think this might have some validity (and at least will spark a debate!).
(And I'll put out that I think abortion is wrong - but I'm interested to see where this will lead us)
Abortion violates Christian values, only because we have come to the conclusion that life starts at contraception. However, people of different faiths (or no faith) may not believe that at all. For the sake of argument, pro-life seems to be mostly pro-religion. In other words most supporters of pro-life are so, because their beliefs come from their religion.
Thusly, playing the devil's advocate, I will put out the following:
Abortion must be proved that it violates a principle accessible to people of all faiths, and of no faiths. Therefore, if some people believe that life does not begin at contraception, the principle that life starts in the womb may not be applicable to them. What then, for all people, are other principles that abortion violates, exempting the belief that life begins at contraception?
