My main point in writing is to strongly recommend a little-known and excellent "pro-life" organization with a very fresh approach, one that avoids all the negatives of the mainstream pro-life movement that has resulted in so much division, polarization, and animosity. It's called Feminists for Life. They have a real gift for finding common ground between people across the political spectrum who disagree on the abortion issue and have a very fresh, non-judgmental, and non-ideological approach. They can be found at: http://www.feministsforlife.org/index.htm
As for me, briefly, in order of questions:
I don't think there are any "spiritual" aspects of abortion. I think through the moral aspects based on my belief (I am a Catholic Christian) in the dignity and intrinsic worth of every human being in themselves. This is the same belief that explains my opposition to racism, sexism, child abuse, slavery, capital punishment, exploitation of the poor, etc. Who is a human being and who isn't is a question I believe that can be answered through reason and good empirical science, as long as it isn't hindered by ideological blinders. This is why I believe a human being comes into existence at the moment of conception and is no longer present after natural death.
People who "feel" differently? This is a category mistake. We don't - or shouldn't - "feel" our moral judgments on anything. If you mean "think" or "judge" differently, then yes, I would like to understand their reasoning when it comes to determining who is and is not a human being. In my experience, "pro-choice" adherents do not even seriously engage the debate at this level.
I would like pro-choice supporters to understand that when it comes to everything else about the issue - the rights and interests of women, especially in the "tough cases" of incest and rape, I share their sympathy, outrage, and understanding of the tragic and impossible situations women find themselves in. The first tragedy is that women find themselves in situations where they need to make such a choice in the first place - either their needs have not been met in some fundamental way, or they have been used or abused by men - both moral evils that need to be opposed.
Again, I think Feminists for Life provides a new frame of reference that can bring people together. Take a look at their website! Their founder would be an excellent interview.
