A 1994 C-span documentary examining the history of political correctness, an ideology that expanded in the late 20th century and has continued to expand through the 2010s.
Contrary to popular belief political correctness does not have its roots in 1960s hippy culture, but during the 1930s at the Frankfurt School in Germany, a headquarters for Communists scheming for a fresh approach at implementing their Marxist ideology across the west.
Political correctness is simply a mask for "cultural Marxism", a twist on classical Marxism from economic into cultural terms. It was devised with a different approach and never used the name Marxism because the original ideology had been so discredited. While at face value they look like different ideologies the binary core principals remain; victims and oppressors. Cultural Marxism, or Political Correctness, says that all history is determined by power, by which groups defined in terms of race, sex, etc., have power over which other groups. Nothing else matters. All literature, indeed, is about that. Everything in the past is about that one thing.
Just as in classical economic Marxism certain groups, i.e. workers and peasants, are a priori good, and other groups, i.e., the bourgeoisie and capital owners, are evil. In the cultural Marxism of Political Correctness certain groups are good – feminist women, (only feminist women, non-feminist women are deemed not to exist) blacks, Hispanics, homosexuals. These groups are determined to be "victims," and therefore automatically good regardless of what any of them do. Similarly, white males are determined automatically to be evil, thereby becoming the equivalent of the bourgeoisie in economic Marxism.
