I’m talking about Europe though, again, re-read my comment.

In other words, denying the Dark Ages is denying historical evidence, most of the times with a political or religious revisionist agenda behind.

Bryan Ward-Perkins, The Fall of Rome and the End of Civilization (Oxford University Press 2005), pp. 87, 183

[T]he post-Roman centuries saw a dramatic decline in economic sophistication and prosperity, with an impact on the whole of society, from agricultural production to high culture, and from peasants to kings. It is very likely that the population fell dramatically, and certain that the widespread diffusion of well-made goods ceased. Sophisticated cultural tools, like the use of writing, disappeared altogether in some regions, and became very restricted in all others.

…

It is currently deeply unfashionable to state that anything like a ‘crisis’ or a ‘decline’ occurred at the end of the Roman empire, let alone that a ‘civilization’ collapsed and a ‘dark age’ ensued. The new orthodoxy is that the Roman world, in both East and West, was slowly, and essentially painlessly, ‘transformed’ into a medieval form. However, there is an insuperable problem with this new view: it does not fit the mass of archaeological evidence now available, which shows a startling decline in western standards of living during the fifth to seventh centuries…[which] was no mere transformation, [but] a decline on a scale that can reasonably be described as ‘the end of a civilization’.

…

[T]here is a real danger for the present day in a vision of the past that explicitly sets out to eliminate all crisis and all decline [like this]. The end of the Roman West witnessed horrors and dislocation of a kind I sincerely hope never to have to live through; and it destroyed a complex civilization, throwing the inhabitants of the West back to a standard of living typical of prehistoric times.

They were dark for Europe though, that is undeniable.
