A lesbian is raped and gets pregnant. What is the "best" thing to do?

You know, there’s an awfully high number of people who voted abortion but who haven’t commented explaining that decision. So would anyone care to explain? Is it because of the mother’s sexuality, the perception that the baby will grow up evil/a rapist, the perception that the rapist somehow wins if the child lives and his genes are passed on? Or is it more of a personal thing where you are considering how you would act in that situation?
