Let's make this 'Explicit'...shall we?
Like question and no answers? Or do you like questions with no answers?
They all have answers it's just in this day and age of 'PC'. people don't like 'actual answers or reasons for behavior so it's always 'a problem' in search of Funding or a 'study'. but no 'conclusions' wanted or desired! You can spend more money that way or get more money spent that way!
Well the answers have been there for generations but the answer to this conundrum that I first became familiar with was that of Stephen Goldberg of the City College of New York back in the '80's.
Here's the answer: (both available on Amazon)
'The Inevitability of Patriarchy' and
'Why Men Rule'
He thinks that 'Diversity' in the sexes is a good thing kinda like 'Choice'.
To distill it down for you in a nutshell:
"When girls move in guys move out... It's a 'guy thing'"
Now if you were 'religious'... say a 'Christian' you might say it's a result of 'The Fall', i.e. the human 'sin nature' correspondingly where women can be catty..
Not as intended from the start but still the 'fallen result of' a 'dichotomy' that was built or 'designed' in originally, that's a 'good thing' if it was all guys or gals I would not be here to write about it and you would not be here to criticize it!
As the Frehch say Viva La Difference! Even if we dont understand each other, or think tht guys should be more like girls and vice versa. Well we arent and Im Glad!!!
So now you know The Answer and will never have to ask again, when women find something desirable men wont and they leave for some other area of the Bat Cave that has not been invaded yet.
Men need Space and Women need Connection to solve their problems or to recharge their collective batteries to once again enjoin the battle of the sexes or just to take some needed 'R&R.
You Go Girl!
