Thank you for the question. I am on the side of whatever produces the greatest amount of liberty for all.
In the scenario you bring up, I believe there are many involved: 1) the woman 2) the man who contributed 3) the unborn child (the fetus itself is alive) 4) the families of the woman and the man 5) God
Personally, for myself and anyone I might be able to influence, life is precious and should only be snuffed out after careful consideration of all options. Today, babies are being taken from the womb at earlier and earlier stages of development and being nursed in incubators to become totally healthy human beings. With modern technology making such large advances, it is conceivable that in the not-so-distant future, any fertilized embryo could be transferred to an incubator and nursed to full development. So, personally, I am against abortion of any type.
As far as forcing my ideas on others, no. I am against an outright ban on all abortions.
These decisions about terminating a pregnancy prematurely need to be made by the individuals (<- PLURAL) involved. The fetus does not have a voice that modern science has discovered a way to hear. Abortion should not be the first option, it should be the last option. More emphasis and support should be given to other options, including pregnancy resource centers where women can get monetary support for their needs and health care if they can bear the child to term. If the child is unwanted, adoption is a great way to go, and some childless couples will pay HANDSOMELY to a woman who agrees to bear the child for them. This becomes a paid service the woman is providing, not slavery.
It is grotesque to think a woman who becomes selfish and gets "cold feet" in the last month of pregnancy could use this as an option. There should be some limits.
