at the risk of being lectured further by people who only post here to hear themselves talk, i'll chime in because it's directly related to what i was thinking last night:
the pro-choice movement has IMO completely ceded the soul of the argument to the other side, and as a result spends all of its time quibbling over details instead of the broader issue.
i obviously don't agree that a zygote is equivalent to a toddler, but i understand that to the people who DO think that a zygote is a toddler (whether genuinely or out of malicious intent is irrelevant) that trying to argue it with scientific facts is like trying to argue that black lives don't matter using the Bell Curve as your evidence.
no, it's not academically the same obviously, but it's rhetorically the same to the other side of this debate and that's the thing i think a lot of people just don't grasp.
so i personally wonder how the narrative would be different if the pro-choice side stopped arguing from the pro-life position, and argued from the pro-choice side more strictly.
the "pro-life" (pffft) position is that conception and birth, at all costs and above all other considerations for any other factor, is the only morally correct point of view.
this cannot be argued with by quibbling over when adequate cell division has occurred to classify it as "human" or not, nor countered by pointing out that draconian law attempting to implement this philosophy results in untold suffering on others.
to an extent this premise has even been internalized by much of the pro-choice movement at least in the US, personified by the "safe, legal, and rare" slogan.
i have the opinion that this lack of push-back on their central tenet is why regressives are so emboldened with their stance and gratuitous with their attempts to force it on others.
it could be that more rigorous counter-argument in ways that don't cater to their starting position would be more effective - for example, i personally don't give a shit about the question of when life actually starts and will just say that as soon as a sperm hits an egg it's a fully formed baby if that's what they want to pretend, but that abortion is still correct on the basis that we as a society have deemed whole swaths of people as legitimately killable for a variety of reasons and fetuses are just another in that list.
i guess you could shorten that down to i basically apply the castle doctrine to pregnancy.
maybe the national conversation wouldn't change in the US if more uncompromising rhetorical tactics were used.
and maybe that sort of thing isn't possible because most people can't buy into that idea, perhaps i'm extreme in my views.
but, i can't see it as being less effective than the current way people go about it.
