If you control the language, you control the argument

If you control the argument, you control information

If you control information, you control history

If you control history, you control the past

He who controls the past controls the future. – George Orwell 1984

Socialists would never create an army of useful idiots to unwittingly help them commit genocide. And later they would never attempt to rewrite the affiliation of the people who did it. That is just conspiracy theory.
