In my own life I had a 'spiritual' abortion. My first wife and I had a pregnancy out of wedlock. I did the "right" thing and married her. Nine months later my daughter was stillborn. She was fully developed. The doctors couldn't figure out what happened. To be perfectly honest, I did not grieve my daughter's death. If my daughter had lived, I would have been bound emotionally to a woman who was bi-polar and very destructive. My daughter's "decision" to not come into this world allowed me to move on with my life. I've not had any children since, unless you count my adorable kitties.
In the end I do believe in the choice. IMO the higher pitched statistics that are thrown around by the pro-life people are at best murky, mostly disingenuous, and at worst, misleading. The path one goes down with the "abortion is murder" leads to comparisons of human embryos to eagle eggs. The moral decision of choice vs. murder becomes a political football with all the abiguity entailed therein. I also take some issue when the fever level of condemnation about choice is combined with the lack of support for those who heed the pro-life message. Life is not fair, but people are human, and it's a hard enough to get through life already without dispassionate, dogmatic social movements making life more miserable.
