One large-scale study of pregnant rape victims found that approximately 70 percent chose to give birth. Many sexual assault victims see giving birth as a selfless, loving act that helps bring healing from the horrific experience of the rape itself. Women who abort children conceived through rape often report that they didn’t feel that they had any other choice, since everyone around them assumed that they would not want to give birth to a rapist’s baby.
The case against abortion for pregnant victims of incest is even stronger. Incest victims hardly ever voluntarily consent to an abortion. Rather than viewing the pregnancy as unwanted, the victim of incest is more likely to see the pregnancy as a way to get out of the incestuous relationship because it exposes the abusive sexual activity that family
members are either unaware of or unwilling to acknowledge. The pregnancy poses a threat to the perpetrator, who frequently attempts to coerce his incest victim to have an unwanted abortion.
The idea that the violent act of abortion is beneficial to victims of rape and incest is simply unfounded. On the contrary, evidence shows that abortion in such cases compounds the unspeakable pain that victims experience.
