Just a couple of points to throw in here----I'm not sure that this is the best way to analyze the situation, if we hope to use social theories to mount an opposition.

Listening to the Reiner Fuellmich interview with Desmet on Mass-Formation, I don't think that we meet the pre-conditions of having a population which has no "sense of meaning." (He used as evidence a survey of Europeans who thought their jobs were meaningless.) As we've seen, college, family, jobs can be extremely powerful motivators to get jabbed, which suggests that they are not unattached. (I would argue that "social control" theories are a more realistic explanation for what is happening now.)

LeBon was describing the dynamics of crowd/mob behavior, which is a fleeting phenomenon---at some point, people wake up and are amazed that they behaved in an uncharacteristic manner. The emotions resulting from "intoxication" cannot be sustained over a long period of time, and slowly, but surely, people come back to sobriety.

We need to take into account that much of the vaxx craziness is illusion. I have no doubt that human bots are being paid to drum up the perception of a huge number of "true believers." Biden gave the govt. billions to do just this.

So, what do we do, since we don't have leaders or the media to spread a counter-message? I've been doing a little reverse-psychology and telling people variations of how "it's such a shame that the vaccine is a dud," and try to chip away at their beliefs.

Sorry that I don't have better answers.
