Many boyfriends or close male friends seem so different when they are by themselves, as opposed to when they are with a bunch of other guys. I think it has to do with the desperate desire on the part of guys to be seen as a "real guy" - a real man, a man's man.

Many guys see relationships with women as a zero-sum game: If she wins, he loses. Marriage is the ultimate contest: Her job is to get him to capitulate to marriage. So many men see marriage as the "end of freedom," the end of boyhood. That's why bachelor parties are supposed to revel in that boyish irresponsibility "one last time." So many guys figure, "Why rush into something that means basically that you'll be a prisoner forever?"

Some of the worst elements of Guyland rest on the twin pillars of men's silence and women's compliance.

It's like what you might call Goldilocks' dilemma in the old fairy tale. Young men see women as "less than" or "better than," but never their equals. And studies indicate that equality is the best foundation for a healthy relationship.

White men in North America are the beneficiaries of the single biggest affirmative action program in world history. It's called world history.

Ironically, survey after survey shows that married men are happier and healthier than unmarried men. Oh, and they also have more sex.

The pull of Guyland reminds us that women cannot accomplish this transformation alone. In the book's final chapter I argue that just as men need to stand up, do the right thing and break the silence that perpetuates Guyland, so, too, do women need to support each other in resisting its pull.
