historically only women could carry a fetus to it's potential (not inevitable because miscarriages are WAY more common than most people realize, even in the 20th and 21st centuries).
for as long as women have had this responsibility they have understood that it's all a matter of resources. I, as a person already exist, have a history and in some cases have existing children. (I'm speaking as the universal women, now). I, as a person have already contributed to my society and if I have children have to remain Alive to care for them. If a pregnancy threatens that - and puts my existing children in danger, the fetus has to go. Too bad, so sad, but I take precedence. A fetus is just potential. Even Mother Nature knows that.
With respect, that's not really answering the question. Also, it prejudices the argument by presupposing that the only reason for abortion is that the pregnancy threatens the life of the mother (and her dependants) and hence any opposition is inherently "anti-woman". I seriously disagree. First of all, unless the implementation of said law is utterly bone-headed, the necessary safeguards should be in place to ensure that abortions after any legal limit can still be carried out where deemed medically necessary. In short, the situation you describe above should not happen.
Again, given your statement that "a fetus is not a person", the question is, at what point do you consider a live-born baby to be a person?
Is it the moment it clears the birth canal? Is it the moment it takes it's first breath and it's cardiovascular system reconfigures? Is it when it's not entirely dependent on it's mother for survival? When does "it" become a person in your view?
If you have any difficulty answering that, then perhaps you can equally understand why I can't readily share this view that a fetus is not a person. The reason is that this one word covers many distinct stages of human development. Allow me to clarify:
A fetus at 9 weeks has pretty zero chance of extra-uterine survival (even with medical intervention), nor has it developed to the level where we can reasonably suggest it has any self-awareness. It is, as you say, a potential.
A fetus at 26 weeks is still a fetus but in contrast with the above, has on average a 50% chance of survival (with medical intervention) and is more than likely sentient and probably sapient to some degree (adopting positions that it finds more comfortable and deciding to play football with your bladder in retaliation for your eating something too spicy being anecdotal examples).
A fetus in the last few weeks of gestation is still a fetus but is practically indistinguishable from a newborn and has almost the same chance of survival as a full-term, with only the most basic medical assistance.
I don't see how, given the spectrum above, how a fetus in the later stages of development can be considered any less a person than a newborn baby.
I seriously can't imagine you could ever say to a mother-to-be that loses her baby in the final days of her pregnancy "Come now, don't upset yourself. It wasn't a person, you know? Not really. Just a potential. Plenty more ovulations left to try again with."
the reality is that marriage was invented BY men because they needed a way to prove that children "belonged" to them. And religions encouraged marriage because that ensured a continuing membership to the church putting money in the coffers. For this to work, women become property.
I have never bought the 'women as property' notion. I don't bother with any exact 'date or time frame' because it's not up to me. It's a decision that ONLY a women and anyone SHE cares to bring into this can make (doctor, husband). The religious HATE that women are in charge of their bodies and their lives. Well, too bad.
The facts are that pregnancy is not a simple thing and unless it's happening to me why should I have the nerve to tell someone else what to do about an immensely complicated thing? It's hard enough while it's happening - who wants busybodies buzzing around you to annoy you with their fantasies about what THEY want?
None of the above actually relates to the question I was asking :-/
