A 13-year-old girl is not a "woman." She's a girl. A kid. More importantly, according to society she's a minor who is unable to make any life-changing decisions on her own without parental (or guardian) consent, including obtaining prescription medication, driving a car, going to the doctor, going to the dentist, buying alcohol, buying cigarettes, deciding whether or not to have surgery, deciding whether to be a Mormon, Muslim, or Catholic, etc., etc. I don't see a decision regarding what should be prescription medication for an abortion pill or a medical decision to have an abortion as any different.
You seem to operate under the misconception that minors have no rights. That is not correct. I agree that parents should be making decisions for their children, but children aren't slaves and have rights, which even parents can't infringe.
Do you genuinely believe that a parent should be allowed to
force a kid (as you so aptly put it) to carry a child to term and go through labor? Then what? Do you then believe that a parent should be allowed to force this
kid (again, your words) to, for example, breastfeed the infant?
A better question still, since the 13-year old is now a parent herself, do you believe that she - and she alone - can choose to put the baby up for adoption or to keep and raise it herself? Or do you believe that her parents get to preempt her parental authority and exercise it on her behalf since she's still a minor?
Your position - like all absolutists who see things as black and white - is untenable and crumbles away when exposed to a reality that is all shades of gray.
I'm in favor of the broader principle as it applies to all legal decisions regarding the minor child, which of course would include abortion.
In other words you believe that once the parents force their thirteen year old to carry a pregnancy to term, they can their make decisions for the infant as well, preempting the actual parent's right to make legal decisions regarding her minor child.
It simply defies common sense to start drawing arbitrary lines for kids and allow them to make adult decisions in situations like this. What's outrageous too is it may help cover up a crime. A 13-year-old girl cannot consent to sex, so any 13-year-old girl who is pregnant is a victim. Her parents should know. Law enforcement should know.
You raise the point that it would be a crime, and you are right. This is, perhaps, your strongest argument. But let's see how it works in a few corner cases, shall we? Let's assume we are in a State where the age of consent is 15, and the girl in question is 16. Now what?
