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.

Playing along with Guyland may be the only way an individual woman might believe she has a chance at a social life or a relationship. Sometimes it gets pretty crazy, like a sorority requiring that all the pledges sleep with the members of the "brother" fraternity.

Feminism loves men enough to expect them to act more honorably and actually believes them capable of doing so.

My colleagues and I have done a survey of 13,000 students on more than 17 campuses, and we found that while sex in college has always been a bit more casual, "hooking up" has pretty much replaced other traditional forms of dating.

So guys who are otherwise sensitive and thoughtful say and do ridiculously dumb things to impress other guys. It's an enormous performance, but guys know that if they fail, they'll be ridiculed as sissies mercilessly.

White men in Europe and the US are the beneficiaries of the single greatest affirmative action program in the history of the world; it is called the history of the world.

I think there is another choice for women; it involves challenging Guyland and supporting each other.
