I think the OP and topic header create a false dichotomy. Not an uncommon thing to find in debates on abortion. There are not two reasons for opinions on the issue of State control of reproduction. There are many opinions, and many philosophical elements of each of those opinions.
I oppose state control of the entire realm of human reproduction. I also feel that every living being, which includes fruit flies, fetuses, and even Southern Baptist Republicans, and Unitarian Pinkos, are beloved of the Lord. That means the issue of abortion is a very difficult issue for me. But the overwhelming thing that I see is that the State has no specific record of expertise in the matter at all. I also disagree with the concept that the State has some right to be involved in it at all. The entire process of pregnancy takes place inside a woman. That seems to be outside the reasonable purview of the rights of the State.
I am certainly not pro-abortion in any sense of the term. I doubt that a significant proportion of the pro-choice faction would be either. I know for a fact that the anti choice community is certainly not commonly pro-life in any supportive and dedicated personal sense in the case of the woman who elects to keep her unwanted child and raise him without family support systems. I know that because the facts of single motherhood in America pretty much demonstrate the absence of pragmatic aid to these children that such a commitment would entail. Life may be sacred, but poverty and social condemnation are evidently acceptable treatment for the sacred.
So my stand on abortion is that it seems the least likely choice to be right to me, but it is not a choice I will ever have to make. I find it unacceptable to surrender such choices to the state. I will support any woman who seeks my aid in avoiding that choice. I think it more important to offer that woman the sort of love and care that she needs to face the real world problems of pregnancy, than to make, or seek laws to compel her choice in that matter. The child, if it is born will have that same commitment from me. Until it is born, I do not see that I have a right to compel her to follow my reasoning. Neither do I feel that I have the right to compel her to bear a child over her specific objection.
There are many that feel very passionately opposed to abortion, and of them, some are compassionately committed to the sanctity of life. Some are passionately committed to their perception of their own moral superiority, and little else. Most others fall in the ground between. As do those on the other side. The test would be the dedication to the people who we are talking about. Not the issue of their rights, but the people themselves, and the lives we contemplate controlling. If we will choose to make decisions compelling these choices, we must first make decisions making those choices reasonable.
I would find the disparity of rational thinking more glaring in the case of those who are Pro-State Pro-control in the issue of reproduction, and anti support, anti compassion in the issues of services to children, and pregnant women. I find that more on point than the death penalty.
