Okay, here's my stance. The decision of whether or not to carry a pregnancy to term is nobody's business but that of the woman and her doctor, and the only say her doctor gets is to tell her the facts and risks so she can make an informed decision about what to do - minus any nonsense of forcing her to watch a film, ultrasound, or listen to any religious "counseling" about "sin."
My opinion as to whether or not some other woman should choose to abort or carry to term is irrelevant. I don't live in her body, I don't walk in her shoes, I don't know what her innermost thoughts are. It is simply not my business.
As I've reminded people on another site where abortion arguments come up, the right to choose also means the right to choose to continue the pregnancy. I would hope that the same people who are pro-pregnancy (ie. anti-choice, as in they don't believe that women should be allowed to have an abortion for any reason) would also be pro-social programs to help the mother raise a child with adequate food, shelter, medical care, and education rather than scorning women who are teen mothers, working poor, or on welfare.
I would hope that these same people would be sympathetic to women or teenage girls who are told by the father, husband, or boyfriend (upon discovering the pregnancy) that if they don't get an abortion, they'll be kicked out of the house, divorced, or abandoned. Some really do have to make the choice between an abortion and being abandoned to live on the streets because the male who was involved decided not to step and take responsibility for his part in the pregnancy, or a teenage girl's father decided he was too embarrassed by his "sinful" or "wild" daughter to allow her to remain in the family home and be helped through the whole thing.
Far too many of these people are fine with a woman being pregnant, but if she's among the poor who needs welfare or food stamps, the refrain heard is often very judgmental, even cruelly blaming her for choosing to get pregnant when she's not in a financial situation to be able to afford to raise a child. This is even more cruel if the pregnancy was the result of rape. I would hope such anti-choice individuals would support increased access to contraception and women's health programs so women have more resources and information to help them make better decisions about their own health. After all, there will be far less worry about whether she might want an abortion if there was never a conception in the first place.
