It's actually a good topic with the opportunity to shed some light on both side's behaviour.
But it's still obvious that there *are* some differences between the genders. In how they percieve and react to certain things.
You can see that separation in education starting in kindergarten - with "boy toys" and "girl toys", with "boy games" and "girl games".
Maybe this really has an impact on how you become in your later life and maybe analyzing it has the potential to help you overcome your own (socially imposed/artificial) "boundaries".
That 'punishment' thing - meh - strikes me as odd, but there might be something to it that the author misses and therefor draws the wrong conclusions.
I hit people with sticks, because I can, not because I need to.
Maybe it's because of that "Boy's game" thing. I don't know.
