When Political Correctness loses an argument hopelessly, its response is to pretend it never happened.
The argument over Communists infesting the State Department in the 1950s is simply not discussed any more. Even the word McCarthyism is very rare now since somebody will always use the label to point to the now undisputed fact that he was right.
The battle to suppress racial IQ differences is to gone that top psychological journals are happy to get lead articles from Jensen and Rushton. Otherwise, it is not mentioned, nor is the earlier repression.
Political Correctness is no more inventive than any other established religion.
All of them used their established power to force forgetfulness on any issue they have lost. The Catholic Church “forgot” Galileo for centuries. It is standard admission that The Infallible Was Wrong.
“The Myth of Race” is another standard tactic.
When J. Edgar Hoover recognized that he was not smart enough to fight real organized crime, he declared, “The Mafia is a Myth.”
Predictably, faced with defeat on all fronts, the establishment has declared that the whole subject of race is a myth.
The myth of the Mafia was destroyed when its leaders were caught in a national meeting in upstate New York, no thanks to the FBI. “Race is a myth” is dealt with by the Mantra, where Political Correctness is exposed as aiming all its fire on countries that are white. They are themselves proving than race is very, very real TO THEM.
