Hi Xoxo, I haven’t read Junger but will keep a look out for it; thanks for the recommendation.  
I agree that nature is very flexible; indeed, that’s why human cultures show so much diversity.  Yet there are also certain constants, and one of them is a distinction between male & female roles.  These often have nothing to do with physical attributes and the assignment may appear completely arbitrary.  The important thing seems to be that there IS a distinction; no further explanation is necessary or (often) even possible.  
Today, however, the western elites have embarked on a project of ‘gender equality’.  My first question is:  why?  Why is that in any way preferable to gender-specific roles?   My next question is:  might imposing such an arguably unnatural system produce significant amounts of psychic stress, resulting in the explosion of mental illness (within which I’d include gender identification disorders) that we see today?
