It rather does, though. If the victim is partly responsible for the crime it follows inevitably that the perpetrator is less responsible. In this equation there is only a limited amount of guilt/responsibility to go around. I don't see how you can maintain that in Hypothetical Scenario X the victim is partly responsible while in Hypothetical Scenario Y the victim is not partly responsible, but the rapist is _equally_ responsible in both cases. That does not seem to add up. As soon as you assign any blame or responsibility to the victim, you are taking it away from the rapist. That's actually pretty much _why_ it's specifically a huge problem to assign blame/responsibility as opposed to discussing the purely practical question of situations in which crime is more or less likely to occur.
