Well it should be obvious that the feminist article is being alarmist and unreasonable, just because it is a good idea to take care of your self and others doesn't mean failure to do so is "fault" or "responsible" or "guilt". They are simply making things up that are not there. It seems quite paranoid.
I suppose you could say the advert itself doesn't do enough to shame the rapist, it kind of dismisses the callousness of rapists as to be expected.
But really? Can ANYONE be sure that if they are utterly vulnerable with horny drunken young men NONE will EVER take advantage of the situation? Is it not a reasonable expectation to fear being taken advantage of if you pass out? I certainly do though I'm likely only to end up stripped naked and duct taped to the wall with a cock drawn on my forehead.
Drunken teenagers are not known for their self control.
But I wouldn't say this is so much rape "culture". A human propensity for violence (with puberty extends to sexual violence) is not learned, it is merely the LACK of decency towards other people. People must be taught to RESTRAIN their violent tendencies. Toddlers will spontaneously resort to hitting and shoving their playmates to spite never learning it from anyone, because it is fundamental human logic (animal logic, even) to take what you want by force. Violence is not an "infection" it is nothing special, it is the LACK of self control. When we grow up we learn not to hit, not to hurt and not to touch without permission.
The problem is the perpetrators are so inebriated with dutch courage it is very-hard to reason with them with compassion, they will delude themselves that "it isn't rape" or that "they wanted it earlier" and similar drunken delusions of implied consent. Telling drunk teenagers not to rape is like telling drunk drivers not to be speed, they will convince themselves they are going at a safe speed. Ideally, don't let a drunk person behind the wheel, don't let a drunk man alone in a room with a passed out woman.
I think the best you can do is TERRIFY them with threats of long incarceration under rape charges if they UNDER ANY CIRCUMSTANCES sexually touch a passed out woman. Fear is a powerful emotion, and can resonate even in the compromised mind of a drunk.
BUT! Big Caveat: this ad campaign must make a point that those who do this are more than just guilty, they make themselves pariahs and ostracised, that what they have not merely been caught doing what anyone else would have done, but they have done what most would have never done.
That is another thing people fear, being different. Being a "rapist" rather than another one of the guys.
The feminist article in question also fails to clearly delineate between "normal" men and men who would take advantage of vulnerable woman, they are all painted with one brush. If fails to mark rapists as outsiders, fails to champion men of virtue who would not succumb to temptation.
That - in some small way - contributes to a culture where rape is as likely as it is.
