This is very interesting. I could go off on historical tangents, but I won't. Only a little bit: the reference to the Greek Sibyls is also a link to the Greek mystery cults combined with Judaism to produce Christianity. And that, of course, produced the crusades, ultimately the justification for anti-Semitism and consumption of children in the Blood Oath. The Fascist/Neonazi movement was very much from the early nationalism and linked back to the Crusades as a racist/ethnic fantasy.
The change, as noted here, is the paradigmatic explosion of the internet handed the equivalent of the printing press to everyone. These things were all roleplaying games but with only a few players who had, unfortunately, power and armies. Interestingly, they are cocreation events but with no real creativity, simply endless plundering of past myths and archetypal concepts. But that could change if someone much more capable than Trump actually took control.
I need to think about this some more.
