Oh, come on! I realize this isn't a comfortable topic but, if you oppose abortion on the grounds that it is the murder of an innocent life, which it is, but, it's OK for rape and incest, you are, in fact, saying, in those cases, murder is OK, by definition, lives worth a lower value, ie, Ok to abort.
You're not going to find anyone who thinks abortion is more horrific than I do. I used to be totally against it. However, over time, my thoughts kept coming back to land of the free, home of the brave and the individual rights of our society. In a free society, if that society says to a woman 'you MUST bear this child' against her will, based on whatever set of arguments we like, religious, fairness, the law, as we read it, etc, then, everything after that, ANY choice is subjective to the society. What we eat, what we drink, what we read, say, hell, think.
I am ALL for public service airing of the facts, the health risks, promotion of adoption, contraception and abstinence; all the facts, all the truths, all the opinions. And then, it comes down to, MUST come down to...her choice.
That the debate suffers from pro abortion bias does not make the case for public authority over a woman's body any more reasonable.
I would argue that the truly anti abortion movement should promote the case by saying "We don't want your crack babies anyway and anyone who would choose to murder their infant has no business being a mom either."
People, free people, reject being told what to do and the more personal it is, the more they reject it.
