I think people are missing the point of what she was saying, and that is to be aware of what is going on around you and to take proactive measures to avoid getting into a bad situation. I don't see how that can be taken as bad advice. The alternative is to tell girls to ignore their environment and not to take precautions, because it is the rapists responsibilty not to rape. However, that is cold comfort after the fact. No one would advocate walking through a bad part of town at midnight with all your bling hanging out on the grounds that it is muggers who are responsible for mugging, not you. Most people understand that it is better to avoid being mugged as best possible under the circumstances you find yourself in. You are not responsible for being mugged but you are responsible for not exposing yourself to that risk, as best as you can.
As far as clothing and how you dress affects rape, it is not black and white. An active predator won't care how you dress, they will act on opportunity because they are hunting victims. The serial rapists that make the news are all active predators. The thing is, most rape is not carried out by predators, it is carried out by regular guys on an irregular basis, and they will mostly respond that way when their interest has been aroused, not because they are actively hunting. When someone dresses in a way intended to attract sexual interest they are going to recieve it. Some of that interest is going to be wanted, but most of it will be unwanted. There is no filter for that. And some of that unwanted interest is going to come from people with shaky boundaries, and that could lead to sexual assault in one form or another. Mostly verbal, but sometimes more than that. A woman walking down the street in a sexy revealing outfit is going to be attracting a lot of attention from men, and that attention is going to be specifically because they are sexually interested in her as a result of her dress, not because they admire her mind or her skills. For some guys it is going to be more than just looking, some guys are going to say things, some are going to pursue, and yes, some of those are going to try to force their presence on her.
So, what this woman is saying (and others like her), is that you need to be aware, aware of how you act, where you act, how you are percieved. She is saying that walking like Bambi into a pack of wolves is just plain dumb. Maybe Bambi has the right to walk into a pack of wolves, but that wont stop her from being eaten. It is better to avoid the wolves, and to avoid being Bambi, unless you are Bambi armed and ready to defend. It DOESN'T mean that you can't dress in a certain way, but it DOES mean that you need be reactive and proactive if you do, otherwise you might have an experience you probably aren't going to treasure.
