Unfortunately I have to agree with both sides here. I feel that men's attitudes to rape need to be changed - that they know they can't get away with it, that women should be treated with respect, and so on. Socitey as a whole needs to be more responsible in the way it portrays both sexes. I particularly dislike the constant portrayal of women in magazines as ornaments to be looked at and played with - it only encourages the mindset that all women should be treated like that in men, and the mindset of oneupmanship in women and girls (and in this case I dislike it because it causes women to hate their own bodies).
However, I still agree with Crashfrog that women should know how to defend themselves. The proper training can be applied to any threatening situation, not just rape - consider the response of a woman to being mugged, for example. This is not similar to a drug-rape where no effective defense can be mounted; the knowledge of how to disarm and disable an attacker is suddenly very relevant.
I find as well that the good exercise obtained from martial arts training goes a long way towards making women feel better about themselves, thus its benefit is two-fold.
