Of course there are women...and men...who get drunk and have sex that they regret the next day. That isn't rape, and no one says it is. Well, I reckon it's possible a woman could accuse a man of rape in such a situation, but I'd say that's pretty rare.
Any guy who has sex with a woman who is completely out of it should have his balls cut off.
All of that being said, I don't think it's a bad thing to counsel women...and men...not to allow themselves to become so inebriated that they have no control of a situation. That doesn't make them less of a victim should something happen to them. It does, however, add to the risk that something might happen to them. There's a difference. It's not a good idea to get on the subway and wave your diamond ring around for all to see.
