By Neil the Ethical Werewolf Defenders of parental consent laws often compare abortion to tattooing, ear piercing, or any of the medical procedures for which many states require parental consent. They claim that if we require parental consent for a girl to get a tattoo, we should also require parental consent for an abortion. What I’m going to show here is that our reasons for requiring parental consent for tattoos are absent in the case of abortion. If you believe that an adult woman has a right to an abortion, you should believe that a teenage girl has that right as well, even if her parents say otherwise.
