I really feel some posters are misrepresenting the views of those who have objected to certain remarks relating to women's dress, etc.
The law says that if a woman was so drunk that she could not have consented to have sex, then that is rape. I agree that a difficulty arises in assessing whether the woman rendered herself so physically and mentally incapable that she could not possibly have given consent. I have no objection to someone expressing this view but I do feel some of you are ignoring statements on this thread that have nothing to do with evidential difficulties but which are very judgmental and prescriptive as to how women should conduct themselves.
Some people have suggested that if a woman wears very revealing clothes, she should not be surprised, having "displayed all her goods in the shop window" - I think that was the phrase used, when someone takes her up on her allegedly implied "offer". Another poster said something similar, only this time describing the woman as "oven ready". If, in addition to wearing revealing clothes, a woman behaves in a way that some people consider "provocative" it has also been suggested that it might be reasonable for a man to conclude that she is "up for it". These comments have nothing to do with evidence that might be difficult to substantiate in a rape case and everything to do with notions of how a women should behave, unless she wants to be seen as "asking for it".
Once people start expressing opinions as to whether women should be more "sensible" about their mode of dress, their alcohol consumption and their general demeanour I think it muddies the water. Rape is a crime - wearing revealing clothes and getting drunk are not. It also seems to me that there is potentially no limit to the restrictions that can be placed on women to try and ensure their safety. To some extent, that already happens. Women are told not to walk alone at night, to be careful about what tube carriage they get on, to sit near the driver on a late night bus and not to sit upstairs, etc. etc. It seems to me that this approach places the emphasis on women restricting and adapting their behaviour in order to avoid attack, rather than on men being responsible for their own actions.
