well think about that a moment.  How can two drunk people have sex with each other then?  Because a significant portion of the Canadian population were conceived by drunk or semi-drunk parents.  You're saying when you're drunk you have no responsibility at all, so that should go with men and women, allowing the both to seek prosecution the other one at the same time ... or allowing one to rape the other legally ... complicated.  Clearly you can have alcohol in your blood and not become instantly helpless and blameless.

however the issue of being unconscious is completely difference in my mind.  clearly sexual assault to touch anyone in such a state, clearly rape to engage in sex with unconscious person.
