The purging of our history is deliberate. It is as if those that are doing this used Orwell's "1984" as an instruction manual.
A few quotes I think are relevant:
"If thought corrupts language, language can also corrupt thought".
We see language being used to corrupt thought all the time now. Redefinitions of CRT, DEI, victims, right and wrong. We see voices and language being shut down, banned. Comedians fired for speaking poorly of The Trump. Of DHS calling for people to turn in people in to be fired for not acquiescing to Trump.
"Who controls the past controls the future: who controls the present controls the past".
And this is the operating principle of white washing America's history. This is the point. To control. Which leads to the desired result:
"The lie passed into history and became truth".
Or an erasure of history in the above case. This is the utter corruption. A record of history - burning and floating away until nothing is left of our true history. Only what we are told was our history.
"The Party told you to reject the evidence of your eyes and ears. It was their final, most essential command".
