I believe the changes made to classic literature, over the past few decades, was a political warmup, with the long term goals of revisionist history and full scale censorship. The first changes were justified, by the subjective standards of Left wing PC. These words are offensive. This led to revisionist history; party reinforcing their own fairy tales, and then to full scale censorship, as was witnessed on Twitter before the 2020 election.
The scam started out innocent enough, under the guise of not hurting the feelings of Left wing constituents. This morphed into censorship of an entire political party, because what the Right believed, which is classic thinking, was programmed to hurt the feelings of Lefties. Censored was justified; Pavlov response.
Does anyone on the Left still think the Twitter censorship was justified, based on how you were conditioned to feel about the evil Right? The Left plays long ball and often sets the ground work, early, in ways that slowly move the boundaries of common sense. Often one does to see the glacial damage until, you are told this is now the new norm.
It is better to treat people as healthy adults and not as neurotic children paralyzed by words. It is better to expose and desensitize young and older people, so they can have an adult discussion about classical literature, which gives everyone a glimpse history. This allows us to see where we came from, and draw a line to the present. Revisionist history and censorship tries to change the past and therefore the change slope of the curve, in an attempt to hide data that would undermine their scam.
For example, in Huckleberry Finn, the main character, Huck did say the N-word, often. However, his black friend was not bothered by it. The N-word was not always defined as the modern Left tries to define it, to create division. Adding new definitions to words, and then having Google search come up with the new definition instead of the one used 100 time more often, was part of the scam. This will create conflict between two people who both innocently assume two different definitions.
Word games and censorship are also designed to act like prohibitions, to create temptation, which will then lead to obsessed over reactions to help reinforce the division. I believe the rank and file Left was unaware how they were being used as lab rats, by those in power, where more power was their end game.
I remember when reading Huckleberry Finn, with the modern slang in mind, I wondered why that large black man took it and did not get mad at Huckleberry or even threaten him, like one would expect in modern times. The reason was the Left had not yet poisoned the well when the book was written.
The Latin word for black is Niger; pronounced with a long I like the word kite. It was mispronounced with a short i, like the work kit, by those who were not educated in Latin. Niger originally was short for black man, with black man not offensive even today.
The modern slang, with the short i and double NN in the middle, was originally made fun of by scholars versus hay seeds. Huckleberry was turned into a bigot due to Left wing word games, since in the book his black man friend saw no harm, but enjoyed accompanying Huck on his adventures. This is the dark side of revisionist history, nearing its end game.
