So it wasn't political hacks that tried to add their left spin to every piece of American history that they could get their hands on? Not trying to be offensive, but the tone of how American history is re-told today is not what I would consider moderate.

Are you considering how some part of history is told, or whether it is told at all? Because they're currently not reframing history, but erasing it. How do you reconcile this with what you consider being an earlier "left spin"?
