As a yoga teacher, teacher trainer, bodyworker, ecstatic dance DJ, and writer, I have been in and around this subculture for almost 30 years,
As the son of a teacher at alternative medicine clinics in and around Santa Fe and Taos since the late fucking '70s who then married a goddamn naturopathic doctor, allow me to say with no quaver in your voice that this guy is overthinking it.
Spiritual beliefs of any kind are nothing more and nothing less than the manifestation of a need for purpose. Full stop. The end. It needs to mean something. That's all. That need for purpose serves as the foundation for a ridiculous amount of human endeavor but it doesn't need to.
Conspiracy theorists are basically apostates. They still have a need for purpose but they think that purpose has been subverted. They've decided the universe is imbalanced because the gods are angry. So they look for angry gods. Fundamentally, every conspiracy theorist is saying the same thing: "the world is praying to the wrong deity." They don't have to be advocates of that deity either; David Icke doesn't want the world run by lizard people, it's just that lizard people running the world makes the most sense to his need for purpose. Obviously things are fucked up because the lizard people aren't taking care of us the way actual humans would. Obviously things are fucked up because the people running the world drink the blood of tortured children. Obviously things are fucked up because Bill Gates is bathing us in 5G to excite the chips in our bloodstream from the vaccines. They take these arguments on faith; they won't assent to this assessment when you press them on it but their resistance to argument will go up just as fast as if you said "jesus wasn't actually the son of God, you know".
Hippies? Hippies have known the wrong gods were worshipped since the dawning of the Age of Aquarius. Before that. Before the hippies it was was the Beats, before the Beats it was the jazz crew. I mean, the Bavarian Illuminati were a group of businessmen and aesthetes who figured the world could be run better than the officials running it so they had a couple meetings and here we are, three hundred years later, freaking out about pyramids with eyes.
Fundamentally, you're going to have more apostates when the New World Order is fucked up. And when central knowledge becomes diffuse, the apostates will pick and choose. It's not rocket science.
