Ok, we've got like five topics going now. We might need to rename this thread. :)
"Though I think that during a very early stage of development (I am in no way qualified to say how early) it is in fact an "It". Not human, except in the most general of definitions (Genetic Identification, comes to mind)."
Well, here's the thing. Though I certainly agree one ought to be reasonably informed on these issues, I think that once you come to that point you arrive at the conclusion that there really isn't an iron-clad method for making the determination. It used to be thought that science would eventually offer the answer (ie, viability) but medicine and research has pushed it back further and further. For example on the issue of viability, the age in which a baby can be born prematurely and be supported with good odds for a normal life is way down. It's in the second trimester for sure. The only truly non-arbitrary distinction to be found is locating the point where the entity possesses finally has its own, unique, DNA fingerprint. After that, the organism is in just different stages of development.
So here is my point: it at the very bottom, a decision by the individual, even the ignorant ones, and there is no hope anymore that science will be able to lay out something definitively that might be able to supercede by empirical experimentation the conscience of the individual thinker.
"Now I understand that you would likely argue against that point based on the idea that the very act of conception itself is divine, and would imply the divinity inherent in all of man exists from the very beginning. I might even be inclined to agree with you."
As you can see, my argument is not on the event being divine, but rather the most significant non-arbitrary point in the process where we can see that there really is something new in the womb.
"The problem arises because you have needed to go through what I think is an incredibly complicated theological process to construct what might be a valid logic-based argument for abortion being against christian beliefs."
Point of clarification. The theological process has more to do with whether or not we ought to value life, how to value it, to what degree, and what to do when someone violates it. I am not using the theological process to establish that the unborn infant should be protected because it is human. I am merely insisting that we need to have a solid reason for not thinking it is human, and so that we can abort it guilt-free does not in my mind constitute a good reason. More on this in a moment.
"I am certain that few of the anti-abortionists out there would be able to construct similarly cogent arguments. ...
If you think I am stretching, just say so."
I don't doubt that. On the other hand, we can't all know everything about everything and yet we all must take positions based on the knowledge that we do have. However, I would agree that a lot more Christians could be a lot more educated if only they wanted to be and this would help in the pursuit of the causes that are important to them.
"The real problem I have with making abortion illegal is that there are some cases where I think that it is justified in much the same way as killing a person can be justified."
Ok, now we've come to a couple of other issues. Now we have the question of how this information is applied in our own civil system and consequently how far a Christian might go in imposing his views on that system. Or, in other words, while I would expect a Christian to nod along with most of what I'm saying, I don't expect the non-Christian to do so.
So first here are some of my own positions. I believe that abortion on demand should be illegal but I believe the law should allow exceptions for rape, incest, etc. I do not believe that Christians who have formed similar decisions about the value of the human life as I have
to take advantage of those exceptions. I believe that Christians have as much right as anyone else to impose their views on the civil system, and as this matter is completely despairing of any hope to be settled by any 'neutral' territory, ie perhaps science, in our society the matter should be put up to a vote on a state by state basis so that individual consciences can be respected. Hence, my most serious objection to Roe vs. Wade, quite apart from the fact that it is a utterly flawed decision, is that the matter was appropriated by just nine individual's consciences, removing even the possibility of the other hundreds of millions of Americans whose consciences are no less competent to form their own opinion on the matter.
I should like the matter returned to the states and after that we can at least battle it out. I believe the pro-life position can win that battle. I believe that has always been the case, hence the need to resort to just nine men where instead of persuading millions you only had to persuade five.
"Yes, I don't think parents of under-18 women seeking abortion should be contacted, or their permission needed, because it is primarily women under 18 that are faced with those unique situations, usually caused by their parents."
Oh, I don't think it is as far as usually caused by their parents. Come on! What about all that underage sex we're hearing about? And you're going to pin it as usually the fathers?

No, I don't buy that. Furthermore, it is absurd that parents need to be consulted for just about every other medical procedure that is out there but here you have one involving severe mental anxiety and potential long term health risks (ie, sterility itself) and the parents are to be excluded? Nonsense. In fact, it has been observed that these types of provisions lead to abuse in an entirely different direction.
Ie, the 19 year old boy has consensual sex with a 16 year old girl who then becomes pregnant. The boy does not want the baby to come to term for a number of reasons, not the least of which is that he will be implicated in statutory rape. He then pressures and pressures the girl to have the abortion and meanwhile keep it secret from the girl's parents, thus making this self-serving ass the sole voice in this woman's right to 'freely choose how to use her body.'
I see your point, but I think a better way to handle it would be to have it as the rule that parents must be notified with a path available for exceptions. If a poor, hurt, frightened woman finds it too intimidating to make her case before a judge that the parents shouldn't be notified because, well, the father did it, I sympathize but that's just the breaks. She's in a bad spot as it is and let's be quite clear what the alternative is: neither judge nor parents learn of the abortion and so the pedophile daddy got away with raping his daughter.
In other words, your attempt here to be compassionate is actually giving Daddy (and rapists in general) exactly what he wants: a mechanism by which his daughter can cover up his crime and no one, not even he, need know it happened.
