I have no skin in this game but:
(1) Those who claim "my body, my choice" should also add this little addendum: "my responsibility". So if the woman who lives by this "code of honor" decides to abort, then that is her decision. But if she chooses to keep the baby, don't even think of going to court to get your penniless meth head boyfriend to pay child support you hypocrite.
(2) In regards to the abstinence argument: it is most definitely still on the table. Keeping it in your pants is perhaps one of the greatest litmus tests of inner strength. Parents who just fuck like bunnies usually have no self control, and will generally be shitty parents that raise shitty kids. Parents who carefully plan out their ability to birth and raise a kid are usually great parents, and their kids will turn out all right. Try to guess which of these two will be in the market for abortions. Yes, this is an argument for abortion, I'm glad you noticed.
(3) Abortions in the case of danger to the woman, or in the case of unlawful insemination: the decision should always be in the hands of the woman, I don't think that most sane people will have a problem with this point.
Now that we have weeded out the unsavory demographics via abortions: I believe that in normal cases the father and the mother of the unborn should both have an equal say in keeping or terminating the pregnancy. The definitions of when it is to late to terminate should be left up to the democratic processes of the local communities.
