This would seem to be part of the "new philosophy of mankind". In times past, the wise teachers taught controversial history as a means of ensuring that it would not be repeated. Today, many Baby Boomers have in their minds that they are a different, more highly evolved human without the foibles and weaknesses of past generations. They are, in Thomas Sowell's words, "The Anointed Ones" who have no need to learning from the past because they are free from "original sin" and would never, ever be so foolish as their evolutionary predecessors (i.e., parents). Sad, because the wise teachers are right, "Those who fail to learn from the past are doomed to repeat it."
I used to think, as Dr. Sowell does, that the behavior of the left was due to their feeling of being special and anointed..Now I think it comes from a lust for power over the masses which we have not seen in modern times in America. Terrible pain and experience teaches us lessons we cannot learn any other way. By now, most kids studying the Holocaust and other painful lessons from history are not going to feel much emotion about it..They are most likely thinking about video games, sex, or sports. However, if these events are mentioned, later on in adulthood, some will think about then and even study them further. People whose relatives died in the Holocaust do not want the world to forget..They have real fear that it will happen again. A controversy has recently been in the news regarding the writings of those who declare that that Holocaust never happened. Is the blackout and censorship going on in this school another way to effect that and to have people forget these awful things so it will be possible for a cruel dictator to wipe out groups he/she doesn't like again? Will people ever understand enough about what is happening to academia and our public schools to rise up and change it? The left has taken over the writing of the public school curriculum and the rules governing the teaching of it..They are destroying our history just as surely as if they had built a big bonfire and tossed everything in and the rewriting of it will be done to suit their political aspirations.
Devastate the world with a cataclysm, e.g., the eruption of a caldera, wipe out 1/2 the human population, and throw technology back 200 yrs; does anyone doubt that humanity, along with the "anointed," wouldn't witness massive wars for resources, slavery and pan nationalism? History is the story of humanity in its concurrent environment.
