It has always seemed to me that young women spend an inordinate amount of time arguing about who and what a real feminist is. I can't tell whose side I'm supposed to be on here.
Men can get temporarily interested in discussing what is real masculine behavior, but usually can't go more than 40 minutes straight, even at a Promisekeepers weekend. This is because pretty rapidly, some guy in the group will reveal himself as an opinionated prick who has no interest in listening to anyone else - often it's the lecturer - and the other guys start wandering away to see if anyone has any beer or cigars or good stories.
Women, OTOH, seem endlessly fascinated by the idea of who has got it right an who hasn't. I think this slows down after children, particularly the second child. The issues which were once so central start to become remote. Beer and cigars and good stories don't become remote. Men are lucky that way.
