Orwellian doublethink in action; Reich-wing ideologues falsify public records and then believe in the new history that they themselves have rewritten.
It’s all of a piece really: the American right-wing is profoundly totalitarian in impulse and thought, up to and including the essential goal of tyranny: removing all defenses against an overpowering state by destroying institutions built to protect individuals; as Josef Stalin phrased it, “We are for the withering away of the state, and at the same time we stand for the strengthening of the dictatorship, which represents the most powerful and mighty of all forms of the state which have existed up to the present day.”
These folks aren’t against truth just because they are stupid (although many are) or just to pwn liberals either: Authoritarians cannot tolerate an alternative system of constructing reality particularly one that can construct an alternate system of authority; e.g., science.
ETA case in point: A top climate scientist quit USDA, following others who say Trump has politicized science.
