This becomes a never ending discussion.
Nobody deserves to be raped or sexually assaulted. It doesn’t matter if she is falling down drunk. But, if we use our common sense, that common sense would tell us that girls should not be falling down drunk in the first place. Not specifically to avoid assault, but for other good reasons too.
This really comes back to responsible personal behavior. Girls, and guys also, if you don’t go out and drink irresponsibly, you will avoid all sorts of trouble you might get into.
It's the same with most crimes. Nobody deserves to get mugged, but wearing a Rolex in a bad neighborhood at night is stupid. Nobody deserves to get defrauded, but answering emails from Nigerian Princes with money to move to the US is stupid. And so on.
