During the 1960s, the education establishment launched its agenda to undermine lessons children learned from their parents and the church with fads like "values clarification." So-called sex-education classes were simply indoctrination that sought to undermine family/church strictures against premarital sex. Lessons of abstinence were ridiculed, considered passe, and replaced with lessons about condoms, birth control pills and abortion. Further undermining of parental authority came with legal and extra-legal measures to assist teenage abortions with neither parental knowledge nor consent.
Customs, traditions, moral values and rules of etiquette, not laws and government regulations, are what make for a civilized society. These behavioral norms, mostly transmitted by example, word of mouth, and religious teachings, represent a body of wisdom distilled through ages of experience, trial and error, and looking at what works and what doesn't.
Customs, traditions and moral values have been discarded without an appreciation for the role they played in creating a civilized society, and now, we're paying the price. What's worse is that instead of a return to what worked, many of us fail to make the connection and insist "there ought to be a law." As such, it points to another failure of the so-called "great generation" -- the failure to transmit to their children what their parents transmitted to them.
