Bottom line... a fetus is a parasite and all the rights belong to the host.
I respectfully dissagree, unequivocally on the first count, and with priviso on the second. When a fetus becomes a human being does not necessisarily have to rely on a spiritually driven idea. As pointed out elsewhere in this post, there are any number of scientifically demonstrabile criteria that can be used to decide this. It is up to society to determine which should be used. By your definition, if taken literally, until the child leaves the womb it should not be considered a human at all (indeed, animals would have more protection under the law than the unborn human child). Communist China in fact agrees with you: until the baby takes it's first breath outside the womb, it is not only okay to kill it, but is mandated by law if it is a second child (the "One-child policy." My goal is not the elimination of legal abortion, by the way, but the reduction in the numbers of them. Specifically, the elimination of abortions of convenience, undertaken for no other reason than the mother doesn't want to carry the child to term.
Which leads me to your second point, that it's the mother's choice. Again, we agree on the principle but not on certain definitions. In my mind, it's about personal responsibility. If the woman is raped, for example, than an abortion should be an option for her. After all, she had no choice (you're for choice, right?). If she engages in consensual sex, than did she not choose to assume responsibility for the consequences of her actions? By the way, I also believe in a man being responsible as well. If he lends his sperm willingly to the creation of a child, he has equal responsiblity to support and care for that child. That should also entitle him to certain rights regarding the child, such as sharing custody, if the parents aren't already co-habitating.
Again, where most people on both sides of this devisive issue differ is on the question of when an unborn child becomes a human being. I understand your position on it. I just wanted to explain mine, without the usual rancor and emotionalism that marks most of these debates.
