But the argument
is different to excising a kidney[1], say. And, no, I'm not one to suggest a super-early point whereby a fully developed sense of self (let alone the mythic 'soul') makes anything post-gamete a person who needs to be protected from the sins of the parents.
As the only claim that I shall give about my own qualification to pontificate, I know at least one individual who is around today who, back in the days before 'he' really existed was subject to a decision (that I was invited to weigh in on[2]) that could have led to the other oplutcome. I don't know if he knows that the decision was considered (possibly) or that I was a drawn into it (probably not with any certainty). He grew up well enough and pursued a worthy and worthwhile career, from information gleaned from the last time I had a conversation directly referencing him, although I also know he has also stood for election under the umbrella of a political party I particularly disagree with![3]
Still (or maybe thusly) I am far from the Pro-Life/Anti-Choice. I say only that
somewhere in the lead up to the point of natural (or physiologically precipitated) birth, there's a switch in balance where they are no longer to be pulled like a bad tooth if nothing other than the potential capriciousness of the mother has changed (if I can use such loaded language, which I honestly believe is rarely actually apt). It is not the point of conception, nor is it the point of delivery. And I've already said that once you get so far through the term, I consider that the practicalities (and needs, and latest medical status) outweigh even the Morality Event-Horizon so it probably no longer even matters on morality alone.
To others, the MEH is far earlier, and they don't care about the Practicality EH (or the greatest amount of Do No Harm possible) because that lies absolutely beyond their chosen cut-off and the only useful take from it is as any available ammo they can produce from it to 'support' their far earlier MEH-inspired target. And handily ignore all the counter-pressures invalidating it.
That's what I was on about. I'm not dictating my own ideal, just reiterating the underlying substance of other 'ideals', from those far more focussed on (and in position to be) remaking legislation to their own prefered ends.
Because this is a Hot Topic that will run and run, and I see no need to trickle through the arguments when we know there is a Heavy Aquifer full of far more, ready to be unleashed if we don't take note of the warnings. I am suggesting it could just be blocked up, smooth the walls, funnel it off-map and we probably won't even gain benefit from floodgating it for future use. It's just more trouble than it's worth, if it's directly threatening our socialising zones.
((To clarify, Rolan, I'm tending towards a point well beyond the 'half-formed' of your discussion-point. The others we're talking about think the formation concerned is a lot earlier, and/or by a diferent metric. By definition, there must
be a middle-ground, 0<=x<=1, but there'll never be an acceptance of where that actually is.))
[1] If we're talking organ/tissue donation, then we aren't really comparing like-for-like until some sort of in-vivo or in-vitro recipient 'vessel' can receive and (for the sake of argument) 'benefit' from the gift. At the moment, it's more like a (possibly optional) appendectomy or the removal of cancerous tissue, destined for no more noble cause than a sample jar.
[2] I was a friend of the father-yet-to-be, and by extension also the mother in an amicable but naturally less strong bond. Neither had planned this, and it was 'awkward' for a number of reasons I won't expound upon. It was very very early on when I was made a part of the 'discussion' and (pre-PlanB) was still relatively trivial in the contemporary sense of what could be done - which I obviously now realise wasn't
actually trivial. I do now feel it was mostly an embarassing involvement on my part in hindesight, as 'ally' of the father, who was far more convinced than the mother that the 'problem' for the couple could be solved. I was dragged into the issue that arose, from a far more mature relationship than they each were individually, as a supporter of his. In the end she decided otherwise, they made the relationship more solid, if not officially official.
Eventually she said Yes to the latest suggestion of his that they marry as well, by which time they had someone old enough to be a page-boy without pestering their slightly less immediate families...
[3] And failed. Which, from my perspective, could be better than the alternate timeline where the 'next best' candidate had the opportunity to try, in his existential absence, and succeeded.
