If you’re having a philosophical debate, you don’t need to look at other countries, argue from a place of logic.
I've been arguing from a place of logic by asking the question about whether a woman in labour should be entitled to terminate her healthy pregnancy and strangely enough almost no one was willing to answer. In my experience it is the people in the "any reason, at any time" camp who don't like it when you try to test the limits of their position. Very much like the people in the "trans women are women, be kind" camp absolutely hate it when you start asking hard questions about prisons and intimate care for disabled people and women's sports.
If you’re having a debate about a practical issue, yes looking at other countries may be helpful. But I’m not sure anyone has solved either of the problems I’ve tried to highlight: how do you ensure all vulnerable women who need an abortion have access to one, and who do you write a law that ensures that parents who are not in a position to raise a disabled child don’t have to, without inadvertently discriminating against the disabled?
I don't think any country has solved those issues, no, and I don't think they can be solved.
Re the first issue, I don't think all vulnerable women who need an abortion would have access to one even if you removed all legal barriers, because the barriers they face are not legal ones.
Re the second issue, I've said all along that up to a certain point in time the only thing that should matter is whether the woman wants to be pregnant or not. But past a certain gestation I do think other things need to be taken into account.
If you are talking about discrimination against disabled people in relation to foetuses, you are in fact acknowledging that a foetus has some sort of personhood and rights. I agree with that. And that's why I think, past a certain point, it's a balancing act. If the baby is perfectly healthy and the woman just doesn't want to be pregnant or raise a baby but has failed to get an abortion within 24 weeks, I would attach more weight to the baby's rights and personhood, as well as not asking members of the medical profession to do something many if not most of them will feel crosses an ethical line. If the baby is very ill or disabled then the burden of caring for it, either for the parents themselves or for the social care system if the parents give the baby up, is correspondingly much higher and that is a relevant factor. Having worked with a profoundly disabled child who was abandoned by his parents at birth and lived in an institution, I wouldn't say I am comfortable with the disability exemption but I understand the need for it.
