I am in favour of abortion to term.
I was using that example to demonstrate how arbitrary the various abortion cut off limits already are. There are children out there who were born at 22 weeks, but that does not, in my opinion, mean that a 22 week fetus is remotely "viable", it means that with enough money medical science can achieve some very unnatural things.
Without sophisticated neonatal medical care, the point of gestation at which the majority of babies would survive naturally is approximatly 32 weeks. My post was in reply to someone stating 26 weeks, where they got 26 weeks from is anybody's guess.
However no fetus is viable for very long at all without a live women's body as its life support system, as is clear when fullterm mum's of health fetuses tragically have large placental abruptions. Therefore it is the mother's body that is the key factor, and I believe in bodily autonomy, hence full term abortion.
