I just see it as being responsible for your actions and having a decent respect for human life. I'm not even religious. I'm agnostic. But I understand that we (humans) are more rare than anything else in this universe. That the organization of matter in human form does not come about by accident, and once a mind emerges within the womb (after a sufficient number of neural connections have been established, and it's not hard to determine when that happens given our technology these days ~3 months) then you have to be a heartless psychopath to not consider the life that is growing inside of you. If they tell me that I don't understand because I'm a guy, I just say that they don't understand because they're arrogant and selfish.
"I never submitted the whole system of my opinions to the creed of any party of men whatever in religion, in philosophy, in politics, or in anything else where I was capable of thinking for myself." - Thomas Jefferson
