I think it's more sinister than that. More along the lines of indoctrinate young girls from as young an age as possible to believe that deviate & promiscuous sexual behavior is the norm. This conveniently prevents/severs the bonds that would normally form between men and women, and since girls have been led to believe that sex is unrelated to pregnancy, also devalues/destroys the bonds that would normally exist between women and children.
When you can't trust the people around you, who do you count on? Government! Bolshevism 101. Trotsky covers it in "Revolution Betrayed," though frighteningly as though it was a good thing.
