Phrasing this so that it avoids breaking the site rules: Some would argue that a failure in birth control is not sufficient reason to be forcibly used as an incubator for nine months, and that the unborn has no right to attach itself without permission. Clearly one cannot argue that permission is given when choosing to have sex, because the unborn does not yet exist.
A similar argument would be leaving your door unlocked in the winter and coming home to find that someone has entered your house in order to avoid freezing to death. The entry might have been a consequence of the unlocked door, but the intruder still does not have the right to be there. Many (most?) citizens would argue that they have the right to expel the intruder at gunpoint, even if it means the intruder will freeze to death. Is the age of the intruder a factor here? Second Amendment advocates would say no.
There is an old saying, "a man's home is his castle." Is a woman's body less so?
A child that is the consequences of your own poor decision making is not an intruder.
the person going into your home is a stranger, you do not know their motivations or if they are a threat to you or your family, so you're acting in self defense.
So.. this is my stance on the whole issue
First off, the woman should be aware that if she has sex, a pregnancy is a possible consequence, so, she should make decisions wisely with that in mind. Contraceptives may lower the chance, but not eliminate it completely. So if a woman is going to have sex, she has to be willing to accept that this may make her a mother.
For an actual married family, okay, prepare to expand your family then, it happens. It happened to my sister, her IUD failed, but you know what? She and her husband sat down, and decided to expand their family, even though they were worried about finances. Know what happened? God blessed them, she had twins, a boy and a girl, and they're absolutely priceless, her husband actually quit his day job to be a stay at home dad to cut down on childcare costs, but.. his small business that he runs from his home took off, so they're actually doing better than they had been before.
For unwed? You know, maybe consider not fornicating or committing adultery?
I see no reason for abortions to be legal on the premise of enabling fornication/adultery, "hookup culture" if you will. If driving abortions out of easy accessibility reduces hook up culture? God be praised.
Now mind you, I'm okay with contraceptives, even morning after pills, anything that works prior to implantation which is when I believe is actual biblical conception (as conception takes place in the womb, but fertilization takes place in the fallopian tubes, even with a fertilized egg a woman is not considered pregnant until implantation)
So those can be used for family planning and for dealing with rape and incest.
But after implantation? Should only be permitted for medical needs, that is threat to the life of the mother (self defense) or fatal anomaly of the fetus (compassion, if they have no chance of surviving outside the womb once born)
as far as "my body my choice"? Well, I used to drink that kool aid, until they started pushing for vaccine mandates. Suddenly it's not my body my choice anymore is it?
Not to mention, in a pregnancy, there are 2 bodies involved.
and one of them is not the woman's.
