I don't think this implies fault? Just that you leave yourself more vulnerable to attack if you are paralytic. Rapists are out there, fact. They will choose to rape, fact. Very drunk females are an easier target, fact. Very drunk females are less likely to remember details that might identify rapist, fact.
I don't think this means women can't have a drink, or even have several. I do think it implies taking a level of personal responsibility for your own safety and well being, to minimise the risk of being attacked. Surely that's just common sense?
