To try to get back to your point and the discussion that you have framed, it hardly surprises me anymore when women blame other women for rape. Women enforce gender norms and gender oppression as brutally as men do, often more brutally. In fact I think that gender enforcement is just as much or more of a same-sex phenomenon than something that the "two" genders do to each other. Women, too, can have a stake in maintaining the status quo--maybe just as much of a stake as men do. For instance, if women can make themselves believe that horrible violence and rape occurs only to "bad" girls who dress and act like "sluts," they can feel safe in an unsafe world. But they must distance themselves completely from those "sluts" and "whores" who "deserve" rape, or else risk becoming one of them. Hence, slut-shaming. It's like showing off what a good girl you are so maybe you won't get punished, too.
