Parents are obliged to take care of the kids they create. If they are unwilling or unable to do so, they must make arrangements for someone else to assume that care.
One should not engage in sexual reproduction - heterosexual vaginal intercourse - if they're not willing to take care of the offspring that they know full well can result.
You're arguing that the irresponsibility of parents justifies killing innocent human beings. It doesn't.
No, I'm arguing that the inevitable - unintended pregnancies - has only three possible results.
- Woman carries child to term
- Miscarriage
- Pregnancy is aborted
Of that list, the second is out of our control (beyond controlling a woman's behavior during pregnancy, and even that is not a sure thing, besides being invasive as hell and probably violating multiple constitutional rights...and still not a sure thing), and the third is unacceptable to you.
That leaves option 1. Ignoring for the sake of this argument the potential rights violation inherent in forcing someone to do something they do not want to do, we'll continue with to your argument about it being the parent's responsibility.
You're arguing from the point of view that they shouldn't happen, but history and all evidence indicates that they WILL happen.
So we must address the issue from that perspective.
You're also arguing that the parents should take care of the child, but history and all evidence indicates that that WILL NOT always happen. And sometimes cannot (like, if the parent is dead, for example dies in childbirth, or from complications thereof).
So, in a situation where the pregnancy has already begun, and the parent(s) cannot or will not take care of the child.
Who does?
Obviously, foster parents.
My concern is that there will not be enough foster parents, so we'll end up with large orphanages, which will inevitably cause some problems for the children in them unless closely monitored.
Not to mention costing the state a decent sum.
Frankly, it's much cheaper to provide funding for abortions, and counseling about the surrounding problems to anyone who expresses interest, to help them make an informed decision.
Downside being, of course, that a potential child does not get born.
But is it better to force the mother to carry the child to term, then place it in an orphanage?
Unless you seriously think that encouraging careful use of contraceptives and/or avoidance of sex will prevent the issue.
Hasn't yet.
