We’re merely seeing the culmination of 50 years of feminist advances combined with economic shifts that have left men unemployed and socially sidelined. Early warning signs were clear in the 1990s when men began organizing — a disconsonant concept, I admit — around grievances about divorce and subsequent custody battles. Fathers were feeling increasingly displaced by child-custody arrangements that often “repurposed” fathers as weekend visitors in their children’s lives.

“Trickle down” may not work in economics but it sure does in society and culture. The lesser regard for men’s interests was also manifesting among younger-aged males as girl power seized the public imagination. School curriculums were being adjusted to become more go-girl and less boy-centric.

In practice, this meant a growing intolerance toward boy behavior in general; complaints that they couldn’t sit still in school like the girls; and an epidemic of ADHD diagnoses and medication of children, mostly of boys (11.7 percent male to 5.7 percent female, according to the Centers for Disease Control and Prevention). Just ask any mom with a son born in the past 25 to 30 years: Boys became suspect, wrong from the start. Or, as I began my 2008 book, “Save the Males,” quoting a then-10-year-old boy: “Men bad, women good.”
