Maybe you didn't mean to use that example, but I think your point is kind of defeated if you say when women are simply being conservative or cautious and append that to a very non-cautious act. Getting sloshed is not the cautious way to go about something whether you are male or female. Your chance of being a victim of a crime (not just sexual crimes) goes up when you get drunk.

Before anyone jumps the gun, I'm not saying that someone raped while drunk is at fault. Only that this is a bad example of someone acting cautious at all. Caution and being protective (or the lack there of) != fault.
