Yes—it’s the old Marxist trick to control perceptions of the masses by controlling the Words and Language. Wittgenstein and the Wundtians and Pavlovians all knew how to accomplish this by 1900..
The destruction of the meaning of Words started long before “Progressive” and “Liberal” were made intentionally incomprehensible and meaningless. The Language has been so butchered by the Marxists that people are unable to process information-—it is only emotions-—never Reason, which surfaces today—like Eastern “logic” where Truth has many contradictions.
The concept of Natural Law Theory—Objective Truth-—Modern Science has devolved into a “feel good” tribal collective ideology.
The Leftists destroy the possibility of logic-—by destroying the meaning of Words-—like “Religion of Peace” or Pro-Choice” or homosexual “marriage” which literally is made irrational from the basic assumptions.
Marxism is the Big Lie-—every word from their mouth is warped to the extreme by their irrational assumptions and denial of Objective Truth/God and Reality.
But that also explains why it is as impossible to communicate with liberals as it is to converse with Humpty Dumpty, to whom "words mean just what I want them to mean, nothing more, nothing less."
