Primitive societies live by the Rule of Might, and the strong prevail. 

Advanced societies live by the Rule of Law, and the privileged prevail. 

Enlightened societies live by the Rule of Love, and everyone is lifted higher. 

Love on, my friend
    The Universe


XOR societies, communities & cultures live by all kinds of rules .  There are vast amounts of studies in the world of Anthropology. Your study is simplistic & shallow.

well “love” is a very abstract catch all prone to attract all manner of biased associations. 
it might be fun to drill down and see where what we call “love” is but a special case. 

my theory goes …

null #love is a speical case of  #agreement or #matches between #BeIng’s

←  just a analytic theory i have been toying with for quite a while.

This is an enlightened “push” in the right direction melding thoughts and ideals with those of the average person, to give them a direction to “hope” in beyond what seems to be happening around them in the world now. It is “ART”.

Your ripping it apart and analyzing it, as if it were a real study, borders on the absurd mark.
