Yep. Is to this day in fact.
Thinking history is just about the past is a misconception. Its also about how society evolves, and how it evolves in hindsight with itself.
Societal change is a constant, and fighting and clawing against it generally never works. History has shown us that objectively
Words change, concepts change no matter how dogmatic, perceptions of things once understood change.... and as it does, we view our history differently.
Is this museum correct to make such a leap? I'm not sure. But historical leaps in and of themselves are to be expected, because they are necessary. History is not "settled" fact, it is an ongoing debate, fueled by discovery and the evolution of society.
Thats an interesting discussion to be had, but unfortunately it seems most here are more keen to associate this with current cultural disputes that will be largely irrelevant in 100 years.
