I completely agree and this is something everyone should remember. Even so, it's fair to say that there is a spectrum when it comes to the ahistoricity of any given historical depiction. A work can be a bit off despite the honest attempt of the artist to make it historically accurate or it can be a grotesque mischaracterization that distorts the context beyond any semblance of the historical reality. G*mers tend to demand the latter while pretending they're the ones championing accuracy.
