My likely unpopular opinion is that while people have rights, these rights can be categorically rescinded in the case when somebody breaks the social contract, and it often makes sense that the way those rights are rescinded is related to the crime. Now obviously, we draw some lines, cutting off someone’s hand for theft is “related to the crime”, but I’d argue it’s a bit of a cruel punishment for theft. I believe that in the case of pregnancy due to female on male rape, the victim should have complete control over the result of the rape. That means opting for an abortion on her behalf (except in cases where it’s impossible or far too dangerous due to outstanding medical conditions), adoption, keeping the child, child support responsibility, and so on.
I know a lot of people will disagree with the abortion clause in the above sentence on the ground that it’s “her body”, and counter with the very “cut off a hand for stealing” or even perhaps bringing up that I don’t agree with the death penalty for murder. (Though I don’t think I’ll get many vehement disagreements on the adoption/keep/etc part). Maybe I am inconsistent, I don’t know, but I really feel that despite any right to one’s own body, the potential to be required to abort on your own dime is a fair and ethical price to pay for breaching that particular law.
ETA: This is all assuming the woman is convicted, of course. Nothing should be forced on a mere charge.
