You're still accountable to your actions even when intoxicated.
Maybe as men we are accountable, but a woman- not so much. A woman who has so much as one beer, and who wants to "get it on" and advertises it even in verbal format- if you act on it, you can go down for rape. Period.
Its because someone has decided that they are not in full control of their mental faculties with so much as one drink, and cannot therefore, give consent.
So basically, for a female, being drunk is almost a ticket out of a bad one night stand that she's embarassed about, and a felony charge for the guy.
