Seems goofy to on one hand 1)Argue for a need for increased historical accuracy and 2)Use an outdated term dismissed by current historiography. Like pick a lane.That is just arguing symantics though as some people clearly do still use the term. I and many others still prefer the term "the dark ages" to "early middle ages" and it's just as accurate as long as both parties know as to when you are referring. It's no different that referring to a soft drink as soda pop, soda, pop, or a soft drink. Different terms all referring to the same thing spoken by different circles. I'm sure in another 10-15 years they'll be calling it something else, as well as something else in 20-30 more. Regardless I think we both know what's being discussed here.
Dark Ages as a term is quite different from calling soda as pop because it is Eurocentric in focus. Other places in the world such as Muslim societies, Japan, China, etc. were experiencing flowering of culture, science and society at the time so calling that period of history the dark ages in a way dismisses these accomplishments because they didn't occur in Europe.
