Personally, I think part of the problem is semantic. "Date Rape" is a common term used to express the outrage and horror of a drunk woman waking up to find she has been violated while semi-conscious, but also to express the regret of a woman who gave in to a semiviolent seduction. The word "rape" is here more for emotional effect than legal meaning: legally the word means intercourse without consent.

In the older and saner days, the real words used for this kind of behavior, words like "seduction" and "violation" had this kind of horror and this kind of emotional nuance we associate with rape. The Sexual Revolution (as organized, no doubt, by Asmodeus, the archdemon of Lust) deliberately denatured such words, until to modern ears they seem quaint or even alluring. "Seduction" was the word used to describe the crime of getting consent from a woman who was not old enough or sober enough to give consent.

Since the old words have been sucked dry of meaning, we use new words, and they are soon to be sucked dry of meaning. All that will happen is that real rape victims will be assumed to be like "Date rape" victims, that is, victims of seduction.
