Haven't read the whole thread, but I read the origional question.
Many Christians believe it is their job to change people. In my opinion, my job as a christian is not to tell non-christians how sinful they are. My job is to reflect God's love for his people, in my choices, and in my relationships.
A non-christian is not going to believe in Biblical law. There is no sense in trying to tell people they are sinning against a God they do not believe in. Therefore, I, as a Christian, can be against abortions for all reasons, but show God's love to a non-christian who chooses an abortion by loving them anyway, and holding their hand through the experience, praying that God will move that person in a way that changes their heart.
I do not condone abortion for any reason, going back to how I, as a christian, should value all human life. But the only people I should openly rebuke for choosing a sinful path would be someone who claims to be a christian, who claims to believe in the Bible.
Furthermore, God, through his son Jesus, will forgive anyone who chooses to turn from their own desires and follow Him. It does not matter to God if someone has had an abortion in the past, murdered 25 people, or for that matter, did nothing but good for people either.
The point is, that the person is cleansed by the blood of Jesus (figure of speech, don't picture us christians bathing in pools of blood here...), not by how much I point my finger at them and accuse them of being a heathen.
The bottom line, is that I feel saddened by people who choose abortion, not anger. Christians who try to make sin fell better by trying to justify abortion in the case of "rape" or some other form of abuse, are weak christians. They would rather try to soften the sin of the person, than trust in the healing power that Jesus can bring to a person's soul. Once again, it is not up to me as a christian, to do anything except show the love that Jesus displayed to the woman at the well (caught in the middle of an adulterous act), Zacchius the tax collector, etc..
