Not OP, but this sounds exactly like what I'd call objective history. Non-objective history is when people simp, say, Alexander the Great as some sort of political-national hero and say we ought to be more like him, he was a genius, he brought glorious Western civilisation and so on. That typically comes with minimising the whole slave empire thing, aristocrat nepobaby thing, and any other unsavoury details there might be about him by modern standards.

Sometimes it doesn't even make sense, it's just someone important seeming who can't object to being misused. Conservative MLK is a a particularly irksome one I see a lot, given that his body is barely cold in historical terms, and there's a very direct line between modern conservatives and the guys that put up sprinklers on their lawn next to the March's route.
