A miscarriage is a completely different situation. I've had two, and yes, was devastated, but these pregnancies were wanted for a long time, I was married, had a house in the 'burbs, a job, and health benefits. Yet even in my grief I knew that each fetus was a fetus, not yet a child, and not able to survive on it's own outside of my body, and hence, not "alive," but part of me. The people at the doctor's office couldn't even understand why it made me sad to lose something that really wasn't anything yet, and I was advised it was God's will; He knows best.
So, let's talk about God's part in this. In God's wisdom, He gave the trust and responsibility of life to women. It is a precious gift, and an honorable gift, and I believe God trusts women to make the right decisions, even when it is unpopular or disagrees with someone else's view. We were all given free will, so we were all given the freedom of choice.
Do you believe in God, and the wisdom of God? If so, how can you put yourself above Him, limit my choices as well as your own, based on an idealogy that frankly grew out of it's own political agenda shrouded in the perceived "goodness" of religion and the church? You know... those priests who led the charge during the Crusades, the holy men who raped and tortured innocent women and children because they weren't Christians, the one's in front of the line in hunting down and burning witches, the one's who did nothing about the extermination of millions of innocent people in death camps, the one's who enjoy abusing little boys and get away with it, the one's... well, I could go on and on.
Let's look at another aspect of it. According to the Catholic church, it is a sin for a man to waste his "seed" yet nothing is done to make them feel as if they were sinners. Should we take away a man's right to masturbate? Should he have to save his fluids and donate it to fertility clinics, or what? Those poor little spermatazoa, all dressed up and nowhere to go when they could be makin' babies! On the contrary, we spend millions of dollars (probably subsidized by our tax money) to make sure "male enhancement" drugs are available, and even payed for by Medicare and private insurance.
How about another case, away from idealogy and God... way back in the "good ol' days" when the Earth was new and people were a novelty, we needed to procreate for the continuation of the species. Go forth and breed! Now, I believe the world is sufficiently populated. In fact, in some countries there were bans on the number of children you could have, and women were forced to have abortions. Were they wrong to do so? Maybe this didn't agree with moral views, but they believed it was for the good of their country and for those who were already citizens.
On the flip side... would you like to be told you had to have an abortion? No? Why not? It's immoral? Or because it's not your choice? The same people (Tom DeLay being one) who stand in Washington preaching against a woman's individual freedom to control her own reproduction are the same men who support sweat shop labor in third world countries where women are forced to have abortions and work as prostitutes. Why is it okay there, and not here? What if it was his wife or daughter? Would he change his mind then?
In a nutshell, if you can prove to me that you are somehow morally superior to me and above all to God, then I will allow you to restrict my rights.
