Yes.
You believe that a 13-year old woman should be
required to function as an incubator for 9 months? That's... extraordinary! And tell me, what then? Should the 13-year old have any say on what happens to the resulting baby, or should her parents be able to just put it up for adoption
Yes.
It's amazing to see someone in this day and age arguing that someone should be compelled, against their wishes, to carry a pregnancy to term.
No.
What, exactly, are you treating them as then?
I'm in favor of the broader principle of a parent making decisions on behalf of their minor children, which they do with medicine, medical treatment, school, religion, food, clothes, language, etc., etc.
While I am in favor of that principle as well, I don't think that parents should be able to
force their minor children to continue pregnancies to term against the child's express wishes.
Oh, and while we're on the subject of broader principles, are you only in favor of that broader principle when the decisions parents make are ones you approve of, or would you support a parent's right to decide his pregnant 13-year old daughter must have an abortion (perhaps against her will)?
