Fathers routinely warn their daughters about dirtbag men, but boys are generally sent out there into the dating world completely blind to the dangers they may face. They're almost never warned about the possibility and consequences of being raped (being punished with child support if the rapist gets pregnant: courts have decided that male victims are also perpetrators at the same time), they're not warned about hypergamic behavior, various forms of abuse, or manipulation tactics. Even their mothers rarely if ever tell them, because they feel women are "better" people and would never do their sons wrong.

I say "rarely" and "almost never" because technically "only a Sith believes in absolutes" but in reality this is pretty much an absolute. I mean, when was the last time a mother even came after a girl for fucking over her son?
