I am going to keep this one brief and crass.
Our responsibility is not to bring up daughters that are good hearted, conservatively dressed, teetotallers. If that was going to keep them rape free, the Amish and Muslim daughters of the world would be completely safe.
Society's responsibility is to bring up sons that never think rape is an option. My daughters, in fact everybody's daughters, should be able to get drunk and lie down naked in front of a room full of men, safely.
If we are raising a society of ethical sons, those men should think no more of sticking their dicks or their digits into any part of her body than they would think of shoving those same items into a pool full of hungry piranhas.
In fact, naked drunk women if front of a room full of men should end up with no more than moustache drawn on their top lip and a blanket tucked around them while a friend is called.
Yes, those daughters should rethink their booze intake and their perchance for public nudity but poor choices are not an invitation to violence. Ever.
