I agree with most of the points in this essay, but he really should have started the process with the adoption of “no fault divorce”. The breakdown of sexual morality in America starts there, IMHO.
No fault divorce is bad, but I would argue its a symptom rather than a cause. The real breakdown in sexual morality began with the invention and introduction of cheap reliable contraceptives in the mid 60’s. If you look at the charts, the numbers of divorces, abortions, teenage pregnancies, and incidence of assorted STD’s all skyrocket from that time on.
No, it was preceded by abolishing laws/taboos against birth control. That made no-fault divorce all the easier to sell.
