Thomas Edsall had a guest essay in the New York Times Wednesday on the growing gap between the political leanings of men and women. He notes a 2016 survey showing that while 41% of first-year college women identified as “liberal or far left” (an all-time high), just 29% of men identified the same way. He also points to Pew Research data showing that most Democrats are female (56% to 42%), but most Republicans are male (52% to 48%).

Edsall then goes on to talk with a number of social scientists who suggest men are more confrontational and violent than women, who generally seek more peaceful and indirect ways of managing conflict.
