You can basically read it two ways. One way is that you're suggesting that she's at fault for being an assault victim (all other things aside about this story). Along the lines of "she deserved it", "she was asking for it", and similar victim blaming.
Another more logical way to read what you're saying is that she should think to see if she's doing anything wrong when she's telling these guys to go away or stop, like conflicting body language.
My only problem with that argument is that very few people purposefully do anything to get that kind of behavior out of someone else that they don't want it from. It's like ignoring the elephant in the room, which is the behavior of the person doing the assaulting.
I've never been sexually assaulted by anyone at any event (and I am female), but I've had plenty of guys hit on me and feel me up and such. If I don't know you as a close friend, "stop" means stop. Doesn't matter how naked or dressed or drunk or sober or sleepy I might be. It is NEVER my fault for being who I am and telling people to stop at the same time. People that can't understand anything like that need to reconsider what they're doing, because they're about to cross a very, very uncomfortable line. And thankfully, every person that has ever tried to do such a thing has stopped. Good thing, cause I'm the type that will eventually break fingers and call the cops no matter how drunk I am over something like that. That is never acceptable behavior. I don't do that to any person, ever. Nobody should ever be doing that to anyone else.
Lastly, please don't read this as any sort of commentary on the actual story in question. I was shocked to read the post originally, but I'm not passing judgment on anyone. Just a general statement.
