Unlike some, I don't find being against a rape exception to be any more repugnant than being against choice generally. It's much more morally consistent to be against all abortion than it is to be against all except a few that are ok. It's one of those carveouts designed to give the squishy middle crowd a Sensible Centrist position on the issue.
But having the view that raped and impregnated women are all part of God's plan, well, interesting God you've got there.
