Like Wilmaknickersfit, I too was quite surprised to read some of the comments on here.
I had expected that the vast majority of people would not go along with the idea that if a woman gets very drunk then she is in part responsible for being attacked. It may be unwise for a woman (or man) to drink too much, for a number of reasons, not least of which is the chance of, for instance, falling down an escalator, getting mugged, etc., but it is not illegal.
I don't believe that getting drunk is a sign of availability - if by that it is meant that a woman is deliberately signalling that she is, as some people have put it, "up for it". It may, though, be seen as a signal to a weak and inadequate man that here is a chance to have sex with a woman who is in no fit state to either give consent or defend herself.
As for dress, who is actually to determine what is unusually "provocative" dress? Is a short dress, a low neckline, skin tight trousers provocative or are women (and particularly younger women) just wearing the sorts of clothes that they see represented in magazines and videos and which they believe make them look cool and trendy? Even the law accepts that a woman's mode of dress cannot in any way be considered to justify rape, and nor can a woman's drunkenness - though it does present difficulties in establishing what actually happened.
I agree it does muddy the issue if both parties have had so much to drink that neither of them is really in a fit state to either check that consent has been given or to give consent - but that is an evidential issue rather than a judgmental one based on a woman's dress/demeanour.
The fact is that there is an absolutely abysmal record in conviction rates for rape so the dice is already loaded against women. Whilst there have been some mentally disturbed or just plain spiteful women who have been found to have made false allegations, the disproportionate number of acquittals in rape cases suggest that there are probably a great deal more women who have been raped than conviction rates would indicate.
I would just add that I was disturbed to see the demeaning and dehumanising term "oven ready" being used to describe a woman.
