In my opinion rape is a heinous crime, under all circumstances - and it does tend to be about power rather than sex.
The trouble is that many people, of both sexes, can mis-use power. Most attractive women are fully aware of the power that they have over men - and some of them are tempted to mis-use it. I think that some young women, who stumble about our city centres at night, half naked, are saying, "you can look, you can get turned on, but you can't touch!" This is an abuse of power ... and a rather foolish and naive one. Nevertheless, any man who responds to this challenge by raping one of these young women is guilty of a wicked crime and should be punished by the full force of the law. As other posters to this thread have pointed out a sense of personal reponsibility is essential here.
I am fully aware that some people are going to tell me that this situation is fundamentally unfair to women. Yes, of course it is! In a sense, biology is unfair to women - sexual encounters, of any kind, are fundamentally more risky for women than for men.
