Patriarchal moral values = Natural Law/Divine Law/Biblical Law/Koranic Law
Matriarchy - the antithesis of the above. (Some might call it legal positivism which allow such ideas as Transnational Progressivism to contaminate the body politic. Transnational Progressivism can only be pushed on a society that has already been corrupted by feminism.)
What is the purpose of patriarchal moral values? Group solidarity.
What is the nature of matriarchy? Degeneracy and then the defeat of the group by a group practising patriarchal moral values.
What is the essence of patriarchy? Moral restraint.
What is the essence of matriarchy? Sexual liberation.
Re: Only patriarchal moral values count as morality
Whether one calls the negative anti-morals of modern culture morality is just a semantic question. I do call this negative morality because I don't know how else to describe it. Of course patriarchy is required in any positive moral system.
