It always starts with "mystery". People want to know more about this or that, so they can leverage it socially to get more power over people. People do this unconsciously. People stop feeling that this is just entertainment or fun. It gets real and they start believing their own made up stories.
When enough people start believing this stuff is real, some people will not care whether it's real or not, they just care about the power they can get. This is how you get from "mystery" to fascism. Fascists know they are lying. They know. They enjoy it. It's power for them. It's addictive.
When people learn that they can lie and get other people to believe their lies, they spiral away from seeking out a "mystery" to just spreading their lies as much as possible, because the more people use the same characters, the easier it is for them to control people. That's why it is dangerous.
What happens when people are spreading lies massively, is that people experience that they are losing power socially, so they jump on the latest trends to gain back the loss. Which causes the lies to spread faster and further. It's like a burning forest, but mentally. Nobody cares anymore.
People stop caring, because they get used to that those people who are still trying to convey facts, are losers in social language games. It's a kind of collapse in regarding truth of high value. Usually, it ends up in war, people get killed, and society resets. They say "never again".
A "mystery" is often spoken about metaphorically as a candle shining in the darkness. Sometimes, a candle in the darkness can burn down a whole forest. It starts like "this stuff is good" and it ends like "my brother, my sister and my mum died in that war".
Since we learned to use fire, humans have told stories around the campfire to each other. The fire became a symbol of the human soul, because they started to see themselves as alive in the sense that living things are like lights in darkness. Most of the world wasn't. Fire changed how we think.
Prior to the moment of using fire, people might have thought of stone axes as the metaphor for their soul. Perhaps their "souls" where sharp, cutting through the bullshit, had to be made and shaped from young age and when you got old, became fragile, cracking in the skin.
People use technology that give social power as metaphor for the spiritual, so they can control others using language. They build their stories around this language and design it such that people get drawn in. They have to figure out the "mystery". You know.
