I concur with Rebelbase. The act of changing history, which the Soviets so often did, and which the Nazis organized the SS-Ahnenerbe to do in an elaborate and pseudoscholarly way (mythographers of the Germanic ur-Aryans, and all that tripe), was what George Orwell tried to teach us is an abomination and a horror, as it wilfully destroys the human capacity to think inductively and objectively about right, wrong, fact, and error.
Rewriting history is an attempt to lobotomize the revisionist's target audience, and is an act of intellectual violence, not fraud, on a level very nearly with homicide.
