HapticS, yeah, there are several very long mybb threads whirring around on a disk somewhere. I agree with you - there's little to be gained by another iteration of the same arguments. Besides, I'm on a phone and can't type much with one finger.
This is a complex question, freighted with larger issues. Rightly so, in my view, because it's literally a life-and-death matter.
Without trying to draw you, it seems to me that one cannot arrive at a rational (as opposed to sentimental) position on this topic without first identifying some basic philosophical and especially anthropological positions and their implications.
I fully grant you that few issues are more vexing, and no decision is easy or lightly taken.
I've thought long and hard about this very issue for decades, and have had to deal with it several times in a personal and not just theoretical way.
Perhaps the two most basic questions any serious examiner needs to consider and decide are:
1. What is a human being exactly? This includes subsidiary Qs such as When does one start being human, and When does one cease being human? Is one's humanity and the rights (if any) that flow from it, a social construct, and therefore susceptible of and subordinate to social redefinition or even termination? Or does one hold rights natively, independent of any socially-defined rights regime?
2. Is it morally licit for any human being to intentionally kill another human being who has not initiated force or the threat of force?
The answers to these questions have profound implications not just in the immediate abortion debate, but in almost every aspect of human social living ... economics, war, politics, crime, families, children, etc, etc.
My own position is unequivocal and clear. I have made my decisions, and accept the implications, and also the responsibilities they imply, which is why I do what I can to support those women and their children who face the awful dilemmas that can lead to abortion.
