As with many semantic corruptions, the left started it. They trivialized the term "denialism" by applying it not to the denial of a real tragedy, but to skepticism about an imagined climate doomsday. I would like to rehabilitate the phrase a little bit, if I could, by applying it to the denial of an historic phenomenon as real as the Holocaust and potentially as tragic.
I refer here to the havoc wrought by the 1960s. Havoc came in many forms: the zeitgeist shift that undermined personal responsibility, the programs that undermined the family, and the social upheaval that glorified casual sex and single parenthood.
