In my experience, males are just as emotionally-vulnerable as any other gender. Without male emotional vulnerability there would be no country music.
What the people promoting this notion miss is that most males spend years trying to be, or trying to at least act or appear, emotionally strong, brave, and tough. There are many good reasons for that, not the least being because these are things that appeal to women.
It's not just cultural, though. There's a biological substrate to it, obvious to anyone who has raised kids. Guys work to be emotionally strong in the same way they work to be physically strong, and to be tough in their effectiveness in the world. It's their job. Might be womens' job too, but that's another subject.
So enough of this baby-talk, Princeton, unless you wish to become a high-end kindergarten..
