Here is a problem, at least prima facie, for the abortion argument; unborn babies before 24-weeks can feel pain:

“Unborn babies may be able to feel pain before reaching 24 weeks, say scientists – meaning they could suffer as they are being aborted. Until now, the consensus of medical opinion has been that foetuses cannot feel pain before 24 weeks' gestation, after which abortion is illegal in Britain except in special cases. But two medical researchers, including a 'pro-choice' British pain expert who used to think there was no chance foetuses could feel pain that early, say recent studies strongly suggest the assumption is incorrect. The studies indicate unborn babies might be able to feel 'something like pain' as early as 13 weeks, they say. Women going for abortions who have reached this stage of pregnancy should be told the foetus could experience pain while being terminated, they argue. And medical staff should ask if the woman wants it to be given pain relief. To carry on regardless of new evidence 'flirts with moral recklessness', they write in the influential Journal of Medical Ethics. Last night, anti-abortionists said the scientists' claims should change attitudes towards abortion and the practice of it – suggestions that were swiftly rejected by the country's biggest abortion provider, the British Pregnancy Advisory Service. The lead author of the controversial article is British professor Stuart Derbyshire, who has acted as a consultant to the Pro-Choice Forum in the UK and Planned Parenthood, a leading American pro-choice organisation. In 2006, he wrote in the British Medical Journal that avoiding talking to women seeking abortions about foetal pain was 'sound policy based on good evidence that foetuses cannot experience pain'.”
If these studies are accepted, then the feminist would have to advocate giving the foetus an anaesthetic (but why not kill adults painlessly then?), or more likely, just say that abortion is sacred right of women, and it does not matter if another being suffers pain and dies, because abortions must occur, though the universe crumbles. The value of an abortion, thus trumps all other values, being a foundational value of feminism to keep women in capitalism. Ok, that is immoral, but logically consistent.
