No I don't. I could never support abortion. To me that unborn foetus is a potential precursor to a successful human being. Of course the complete opposite could happen but I believe that no one should have the power of life and death over it and deny it that opportunity, irrelevant of how small the chance is. If the parents really cannot take care of it, they may give it up for adoption. I would agree that it should be an option in extreme cases, such as perhaps if the pregnancy came about because of rape or if the mother's life is in danger.
I respect your pro-life position. I hope we still share the belief that both should be held equally responsible.
My philosophy on abortion in general is almost exactly like Peter Singer's. I didn't read him and then change my position, I've just always had this belief. It's very coherent and basic ethics. Here:
Consistent with his general ethical theory, Singer holds that the right to life is intrinsically tied to a being's capacity to hold preferences, which in turn is intrinsically tied to a being's capacity to feel pain and pleasure. In his view, the central argument against abortion is equivalent to the following logical syllogism:
First premise: It is wrong to take innocent human life.
Second premise: From conception onwards, the embryo or fetus is innocent, human and alive.
Conclusion: It is wrong to take the life of the embryo or fetus.
In his book Rethinking Life and Death Singer asserts that, if we take the premises at face value, the argument is deductively valid. Singer comments that those who do not generally think abortion is wrong attack the second premise, suggesting that the fetus becomes a "human" or "alive" at some point after conception; however, Singer argues that human development is a gradual process, that it is nearly impossible to mark a particular moment in time as the moment at which human life begins.
Singer's argument for abortion differs from many other proponents of abortion; rather than attacking the second premise of the anti-abortion argument, Singer attacks the first premise, denying that it is wrong to take innocent human life:
[The argument that a fetus is not alive] is a resort to a convenient fiction that turns an evidently living being into one that legally is not alive. Instead of accepting such fictions, we should recognise that the fact that a being is human, and alive, does not in itself tell us whether it is wrong to take that being's life.
Singer states that arguments for or against abortion should be based on utilitarian calculation which weighs the preferences of a mother against the preferences of the fetus. In his view a preference is anything sought to be obtained or avoided; all forms of benefit or harm caused to a being correspond directly with the satisfaction or frustration of one or more of its preferences. Since a capacity to experience the sensations of suffering or satisfaction is a prerequisite to having any preferences at all, and a fetus, at least up to around eighteen weeks, says Singer, has no capacity to suffer or feel satisfaction, it is not possible for such a fetus to hold any preferences at all. In a utilitarian calculation, there is nothing to weigh against a mother's preferences to have an abortion, therefore abortion is morally permissible.
