@3bodyproblem: No, she doesn't assume that 1 in 6 is a rapist. Geesh, how much more basic can something be explained? Try the roosters problem, really. I'm sure you can't screw that up even if you wanted to.
Well, ok, now I probably jinxed it
And I'm glad you agree that that level of risk would be enough to warrant shutting yourself in, because, well, now you know what women face and they have to function in a society where most don't have the option to live their whole lives shut in. They still have to go to work or shopping or whatever, whether they like those odds or not.
But nobody says that all that works is to not meet them at all. All that works is to not give them a chance to get in a position where they could start the attack. E.g., as she proposes, if a guy comes across as the kind who overrides her saying "no", then basically don't start dating him or anything. E.g., if someone seems to not mind cornering you in situations that make you feel vulnerable, basically don't follow him home and let him corner you there. That was the scope of her article, really.
Really, all it actually says is that you want to pick up a girl for a relationship, don't start by giving her the signals that say such a relationship could be a bad idea.
Now I'm sure there are more immediate measures she and other women take every day, but the actual article doesn't actually go into those. All that it does deal with is, really: so you want to pick up a girl, here's how you can maximize your chances by not tripping her alarms.
If anything, given the usual complaint that women should come with a manual, well, that's what she does there. Consider that part of that manual. Kudos to her for writing it. And sadly the reactions also prove why more don't.
