Saying we need to teach men specifically not to rape is presuming all men are just rapists waiting to go off. You can claim that all men need to be taught this for the few who will and that the other men shouldn't get their egos hurt. But then the same can be said for women.
Women need to be taught not to be prostitutes. The women who aren't shouldn't get their egos hurt.

This article highlights the feminist view on the subject: Women have no responsibility in the matter. Men are at fault. Its offensive to even say that a woman shouldn't be passed out drunk alone at a frat house. No, only the boys should be taught not to rape.
