That point isn’t awfully clear in the original piece, and even so I’m going to take issue with it. I’ve worked as an editor with academics for many years and I’ve always tried to make them understand that you can’t airily declare that words mean what you want them to mean, even if prevailing academic fashions say you can. It’s like Alice told Humpty Dumpty, “‘glory’ doesn’t mean ‘a nice knock-down argument.’” To most educated readers, “distort” means to alter something in order, almost always, to deceive. You can’t redefine the connotation of a widely known word just because you feel like it. And a portrayal of a historical figure in something presented as nonfiction that is distorted—i.e., inaccurate—in any sense is never “welcome.” I’m sorry, but I’ve always been intensely annoyed by the notion that nobody can see beyond his or her situation, that it’s not even possible to understand another’s point of view or portray a thing fairly and accurately. That’s nonsense.
ETA I haven’t seen the film either, I’m just responding to the opinion piece.
