I think the way "Rape Culture" is actually used is to describe all of society not just university campuses. You just hear/see it most often on campuses than in the real world. I agree campuses could bear the label of "Alcohol Culture" but then so could large parts of society.
I think it is could for women to take some self-defence courses. I do worry that TV and movies will cause them to believe that an average women can easily demolish a muscular man half again her weight. When I took a course I got the best piece of advice you could ever get - the first line of defense is running not fighting. After that I think women's biggest weakness in a fight is that most of us have never been punched for real and that first time it happens it shocks you so much you freeze. So practically the best advice I can give is: learn to run, learn to take a punch. And when you decide to run just leave your stuff behind - you can always get a new bag and new id.
