There are several positions taken in this thread that strike me as irrational – and not all of them on the same side.
First, let’s examine the embryo/fetus. There is in my mind no question that it is an organism with human genes, which in the absence of less-than-likely natural causes or of human intervention will eventually become an independent adult human being.
But it is not one yet.
There is a distinction between child abandonment and putting a child up for adoption – the first is the criminal act of leaving a child which cannot yet care for itself without adult care and support; the second is abdicating one’s rights and responsibilities to that child in favor of another willing to assume them.
However, prior to the third trimester the embyo/fetus is not capable of life outside the womb, with another caregiver providing for it. It therefore becomes the responsibility of the woman carrying it to devote her life to its nurture and care, abstaining from what would harm it.
Now, it’s my personal view that terminating its existence by removing it from its natural support mechanism, the uterus, is nearly always wrong – and while we can all manufacture the rare exceptional circumstance, allow me to make that a generalization with unspecified exceptions recognized. Terminating a pregnancy in and of itself is not wrong; what is wrong is allowing the potential human being dependent on that pregnancy for its life to die, and we have no means of keeping a fetus-outside-the-womb alive in our present state of technology unless it is capable of surviving as a preemie. While this may sound like a pointless distinction, it may in the future prove to be a valuable one, as technology improves, and it sets the stage for a point I want to make that is to me important.
I draw a libertarian distinction between holding a person responsible for his or her acts which violate another’s rights, and compulsion on any person to commit a particular act. The first is part and parcel of an ordered society; the second is domination of individual rights by that society.
I believe that, in general, it is the moral responsibility of a woman, having gotten pregnant, to abnegate those elements of her life which would harm the child and to devote her life to the nurture of the child until it is capable of living without her support (which may mean adoption as a newborn).
But, in keeping with the principles above, I believe that deciding whether or not to accept this responsibility is her moral choice, a decision that must be made by her and her alone, in recognition that she alone has control over her body.
I do not believe that we may by law violate the autonomy she has over her body.
And therefore, while anti-abortion, I am pro-choice.
