Things like this make much more sense when you realize right wingers have a different definition of truth than you do.

Truth: statements describing observations of shared experience. (I know there are more complex definitions, but this is sufficient for my point.)

Truth (right-wing): statements describing observations of shared experience that do not contradict claims made by the upper-echelon of their in-group (e.g. MAGA).

So what they mean by a golden age, is an age where the info these agencies distribute is completely controlled by them and is useful to their ends (i.e. domination).
