I see. I think I misunderstood the above statement. My apologies for the confusion. That really makes this much more interesting. If you're not religious then you must know that
life can't possibly begin at conception (unless I'm to assume that you don't mean in a strict sense).
I think that's only one of many issues. I'm actually less concerned with a fetus that may or may not survive than I am with the rights of the mother who bares it.
If a woman's only reason for getting an abortion is physical it is. There are privacy issues that must be taken in to consideration as well.
I'm assuming that we're only referring to the murder of our own species & that you're not referring to the strict definition of the word ("unlawful killing").
While I'm concerned with the suffering of people after they're born, my reasons have little to do with suffering. They have more to do with women's rights. I suppose that an already born human is more "valuable" than a human fetus because there's no guarantee that the fetus will survive.
This whole thing reminds me of Ripley's predicament in Alien 3.
