My thoughts on this is that they are to blame. Of course, each case must be judged on the merits but generally, they must have some blame. If women are getting so drunk that they can't remember what happened the night before the chances are they were too drunk to check if they had the consent of the erect guy before she sat on him. I am not sure of the legal position, but if the UK government is saying that in such situations the woman has no responsibility not to be totally flat-out drunk then the law must change.
