ANY law limits someone's choice. Society balances a person's freedom to choose with the effect that choice has on society. The logic of the whole "pro-choice" position seems to me to lead to a society of VERY selfish people. Oh but wait a minute, that is the society we live in. One of very selfish people.
A few thoughts based on knowing people who've had abortions, knowing people who were adopted out of horrible circumstances, talking with my mother who specializes in counseling sexually abused children after they are removed from their home, having 5 children myself, working in prisons and with troubled youth which many people in society would like to have seen aborted, etc.
In general, those women who get pregnant, are poor, on drugs, etc. or maybe just don't think they can take care of it, but are sincerely worried about bringing their kid up in that environment either give it up for adoption, or tragically, have the baby thinking they can take care of it, don't care for it like they thought it would, then get it taken away.
And in general, woman of all circumstances who don't want to be inconvenienced by the child, kill it in the womb. A society that thinks these woman are doing the child a favor is just a plain sick society.
And although many would like to make this the Rhetoric list. As an Orthodox Christian who believes one day he'll meet his maker, I'd sure rather be on the side of saving babies/fetuses than on the side of justifying the killing of them for people's convenience. And don't kid yourself, most abortions aren't to save the fetus from a life of misery, it's to save the mother from the trouble of taking care of it. And in general people who want to protect a mother's right to murder, are really just worried about protecting their own vices. And some just like reading/hearing themselves argue.
