It strikes me that there are only two stances in relation to the abortion question.
a) Those who say we should be free to choose abortion and
b) Those who say we should be free to live in a world without it.
Those who say that it should be available in limited circumstances would presumably never force someone
to have an abortion. Rather it should be the individuals choice in the difficult circumstances.
a)Each individual should be able to choose what to do with their own bodies. We could suggest that people, if they object to abortion, should avoid it. But their personal objections should not impose on another's personal freedoms to choose as they please.
b)On the other hand we can recognise the humanity and dignity of the unborn in utero (in the womb) and that to acknowledge abortion as a legitimate procedure undermines the freedom of the unborn. Essentially, that abortion is not really a choice we are free to make.
It seems to be a matter of Autonomy of the Mother Vs. Autonomy of the baby.
