Ok. Sure it put some new spin on things. But immoral behavior in regards to sex and how we believe the scriptures and God defines it has been going on for a long, long time. I just do not think it is new since then. We were not a moral prim and proper people about this before that and certainly are not now.
In that case, you have no living idea whatever regarding the levels of crime, juvenile delinquency, domestic violence, property crime, unwed motherhood, premarital sex, and other social indicators up until about 1964 to 65. When I say vast, I mean precisely that, because social pathology, including the breakdown of the family white and black, began a long and unprecedented climb in those years. The late sixties added ideological and philosophical legitimacy to some already existing trends which then gained cachet as revolutionary or progressive forms of behavior and thought.
The sixties were driven by a number of things, not the least of which was a flowering of the concepts and Ideas of Continental philosophy, not the least of which were the ideas of Nietzsche, Hegel, Marx, and the Frankfurt School.
The sexual revolution,, value relativism, the renewed interest in Marx and utopian collectivism; all of these were a part of the mix. There is no "spin". The late sixties were major break from generations past. If you go back far enough, and look cross culturally, you will find similar situations in other cultures at other times, true, but that doesn't change the reality of the massive sea change in values that took place beginning in the late sixties. Ayn Rand properly, from one standpoint, called it the "anti-industrial revolution". From another, it was the beginning of the triumph of a Dyonesian, Nietzschean, anti-rationalist, anti-Judeo/Christian ethos that had a long philosophical history in Franco/Germanic philosophy.
Its effects were also predicted and predictable.
