You can disagree with someone's choice/actions morally while still supporting their legal right to make that choice.
Personally I believe in unrestricted abortion up to 24 weeks, and based on extenuating circumstances up to term.
I also disagree morally with the idea of using abortion as contraception (though I can't imagine this is anywhere near as common as some make out), and feel for any potential father who loses a wanted child (though I 100% believe a termination should be solely the mother's choice and she should be supported in that decision).
I would describe myself as pro choice, but if the above makes me not pro choice then so be it.
I don't honestly know how I feel about the legalities of termination past the point of viability - I'd like for a woman to be able to end a pregnancy at any point with no restrictions, and I'm aware that almost all late term abortions are done for medical reasons ir mental health reasons or extenuating circumstances, and that no woman is likely to take it lightly. But there would come a certain stage in the pregnancy where if the foetus would be viable if birthed at that point, then I do feel that the ethics around termination do change. To very poorly paraphrase a pp on a different thread - for very late term pregnancies the method of ending the pregnancy (getting the baby out) is the same, if the foetus is viable there's no need to commit infanticide in the process.
As said above, though, I'm aware that this would only apply to the tiniest percentage of pregnancies (if any), and also that it's not that simple WRT medical support for both parties, etc.
I don't know what the "right" answer is.
