The passage actually says something like... if the woman doesn't scream then we'll assume it wasn't rape, therefor they must be married. So no, it doesn't actually say "you must marry your rapist", this is just another desperate attempt here.
It is essentially treating the women as if they were being traded like cattle or some other kind of potted good or plant, but no, it is not rape. And this is how women were traded back then, so.... oh well, not my problem.
