The founding thought or action for the creation of the Athenian identity was the abolition of women having random male lovers and thus children not knowing who their father was. I'm sure women were still able to behave this way (have sex with multiple guys) after the new ethical norm was established, and I'm equally sure there was an correction to this behavior by all born without sure knowledge of who their father was were labelled a bastard and locked out of every respectable position in the society, and equally locked out of any route to wealth or fame. They were equal or just a little above a slave.
The repeated phrase in the media that religious conservatives believe "marriage is between a man and a woman" in some sort of following of a God command, and that is the only reason for marriage entirely misses the point. All great societies, some very distant from Judeo-Christian heritage ( Japanese, Chinese, Korean ) are strongly associated with patrilineal kinship.
The ungreatness of matrilineal kinship societies spans every race and every climactic zone of the planet. The Scotch-Irish immigrants of the United States (Appalachia) are noteworthy of their several hundred years of comparatively higher rates of poverty, violence, and lack of grasp of new technology. They are also known for their higher incidence of bastard children.
A society cannot micro-manage people's crafty ways in which they can find time and places to have sex with random and multiple people. What a society can do is label the people born out of such behavior (bastard), and pass over them for anything other than manual labor or cannon fodder in wars.
“I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character.” – Martin Luther King, Jr.
Actually this famous quote is less than half correct and misses the first contingent.
- The status, skills and character of the father of the person.
- The character and skills of the person.
With my commentary you the reader have a greater mental leverage in undoing in ways both small and stealthly and large and legislatively the agenda of Diversity, Equity and Inclusion in it's misdistribution of status and wealth.
Start using the word bastard, and be happy they are in juvenile detention.
