on edit: oops; most of this was of course meant for the original poster.
"Abortion" and "choice" are not the same.
Whether abortion itself is moral is a completely separate issue from whether outlawing/permitting abortion is moral.
And of course "whether abortion is moral" is not an issue that can be answered with a flat yes or no.
Is killing moral? Well, killing in order to acquire property isn't moral; not by most people's moral definition.
Killing in self-defence? Killing to prevent some other killing? Killing to prevent genocide? Killing to alleviate intractable suffering?
Whether any particular abortion is "moral" will depend on the circumstances, regardless of what definition of "moral" is used. An abortion to save a woman's life? An abortion that a woman is compelled, by force or threat of force, to have?
But whether it is "moral" to outlaw abortion, or to permit abortion, is still another and separate issue. There are many things that many people regard as "immoral" (adultery is widely regarded as immoral, e.g.) that are not outlawed.
This is a private decision to be made by a woman in consultation with whom ever she chooses.That's something I consider pretty much a nonsense, unfortunately -- both when it comes to law and, of course, when it comes to morality. Adultery is a "privacy issue"; it can still be defined as "immoral" pretty easily. And there are all sorts of things that people could decide to do, in consultation with whomever they chose, that arguably involve "privacy", that could easily and justifiably be outlawed.
Reproductive rights are an element of the right not to be deprived of life or liberty without due process. That seems to me to be the only reasonable way of defining them. Pregnancy and childbirth and child-rearing (or child relinquishment) jeopardize women's lives and well-being in a host of ways, and restrict women's liberty. Compelling women to accept those risks and restrictions without due process is wrong by human rights / constitutional standards, and immoral by my standards. (The point being that there is no "fair trial" that could ever be held that would result in compelling a pregnant woman to engage in a course of action that could lead to her death, at worst, to a range of physical and mental problems during pregnancy and long after, and to the loss of liberty that is inherent in pregnancy).
My suggestion is that you clarify whether you are addressing
the morality of abortion or
the morality of outlawing/permitting abortion. The morality of
doing (or not doing) something and the morality of
forcing someone to do (or not do) something are virtually always separate questions.
