Women are taught about sexual assault and rape whereas men are not taught (beyond the occasional "if she says no...") for the same reason that women are taught to be cautious of other forms of victimization (such as robbery and aggravated assault) despite the fact that men are the victims of violent crimes (not sexual assault and rape) at a higher rate than women. Noncoincidentally, men are the majority of perpetrators regardless of whether the victim is a man or a woman. And stranger assaults are relatively rare. While people are victimized by strangers, all violent crimes (including rape and sexual assualt) are most likely not stranger perpetrators. That includes people who see you around town but you've never spoken to the person or don't remember ever speaking to the person.
Therefore, women are taught not to leave the house too late whereas men are allowed to run through life "boys will be boys" with no consideration to anything. Men are allowed to sit with their legs wide open to allow space for balls that don't need that much space whereas women are taught to sit with their legs closed. Be careful, women, your vagina may run away or at least the mere sight of that area of your body may warrant a sexual attack. But, men, you keep doing your thing. You're in charge. Sit back and relax.
This has become one of my favorite organizations:

Their videos are on youtube and some of them have relatively strong content. It is wonderful for organizations to work toward waking up EVERYONE and not allowing men to remain asleep while women handle these issues.
Men's slumber (i.e. "boys will be boys" and "let the man watch television while the woman goes crazy raising the children") is rooted in patriarchy, sexism, and misogyny and is pervasive in the family and other social institutions.

ETA: I don't care about that article and that woman's claims about fraternities. The larger issue is more important.
