Wildly overblown claims about an epidemic of sexual assaults on American campuses are obscuring the true danger to young women, too often distracted by cellphones or iPods in public places: the ancient sex crime of abduction and murder. Despite hysterical propaganda about our “rape culture,” the majority of campus incidents being carelessly described as sexual assault are not felonious rape involving force or drugs but oafish hookup melodramas, arising from mixed signals and imprudence on both sides. Colleges should stick to academics and stop their infantilizing supervision of students’ dating lives, an authoritarian intrusion that borders on violation of civil liberties. Real crimes should be reported to the police, not to haphazard and ill-trained campus grievance committees.Too many young middleclass women, raised far from the urban streets, seem to expect adult life to be an extension of their comfortable, overprotected homes. But the world remains a wilderness. The price of women’s modern freedoms is personal responsibility for vigilance and self-defense.
