I don’t know if he said it, However I have said it for several years now...
Eh, it’s an obtuse reference to a George Orwell character. Goldberg was the fictional scapegoat of the totalitarian dystopia novel 1984. The state was in perpetual struggle against ‘internal and external’ enemies. Goldberg was the internal enemy people were instructed to devote their “two minutes of hate” towards. Of course he was fictitious and blamed for most of the failures of the regime. His crimes changed daily. He was a fabrication of the state for people to focus their frustration and aggression against to relieve the angst of their collectively pathetic, state-controlled lives.
