The saddest part for the incest victim is being forced into an abortion by her attacker who is desperate to coverup his crime. Rape victims are 'forced' by society to have abortion because it is 'just expected.' However, throughout history, rape victims (anyone remember Kizzy from "Roots"?) have given birth to their children from rape and loved them as a fellow victim. Even today, slaves in the Sudan love their children that resulted from rape.
I guess I would just like people to re-think these exceptions they keep coming up with. The logic they are using is not pro-life, it is pro-punishment: irresponsible woman deserves what she got.
