How is that different from descriptive moral relativism?
That may be true in some cases, but in this case I believe the enforcement of the immutable law against murder (by prohibiting abortion) strictly prevents injustice. And even if I was convinced that it didn't strictly prevent injustice, I would still have to concede that it prevented a far greater amount of injustice than it caused.
Thank you DM for actually responding to my post.
To your first question, the context (usually) dictates what is right and wrong. You don't get that choice. That is why it is not moral relativism. Moral relativism has a bad name because it provides little guidance on how to act in lifesituations, but surely moral absolutism is no better. In my experience moral absolutes fail you in at least 50% of real life situations. You get the worn out examples of what to do if you are hiding Jews from Nazis and someone asks you are Jews being hidden in your house. Do you lie or do you tell the truth? Calvinists say that conflicting moral absolutes occur because we live in a fallen world and if we get stuck in such a situation, we will have to sin whichever way we go; but, they say, there is no need to worry because if we ask, God will forgive us. What a load of horse ****. Not only is it right to lie in that situation but it is required. The context demands it. Proving that the absoute moral rule that lying is wrong - is wrong. You can say that about any absolute moral rule, thus proving that every rule breaks down in life situations. So what's the point in having any? Moral relativism provides you with too little guidance on what to do and effectively gives you a free for all. But moral absolutism gives you wrong guidance half the time.
As to your second point, I understand. But I am not saying that it would be right for this 11 year old to have an abortion. I don't actually know. I voted yes to the poll because I wanted to give her that choice as it is her context, not mine. Because if you take her choice away, you have imposed a moral absolute on her and we get back to the point I made above.
