CMV: It is okay to abort a baby if you are a minor.

I have read a lot about people who are pro-choice. And most of them agree that if the mother's life is in danger then it is okay to abort the baby, even if it is the unborn child's life in danger. Also, if the mother has been raped and she does not want the child of the person who did it to her, then it is okay to abort. But what about if a teenager gets pregnant? Why should they be forced to keep the baby? They are still children. And most of the time the parents do not support the teenager and it is up to the teenager to pay for the baby. Some of them do not even get to finish school because they are forced to be a mother.
