Gagdad Bod, AKA One Cosmos, has some illuminating (NOT Illuminati) things to say about the far left kooks.
it is very unsettling that a large segment of the population believes things about conservatives that are not only untrue, but cannot possibly be true. They are terrified of a wholly fantasized version of reality, while I am afraid of their seemingly boundless capacity to fantasize and to inhabit their malicious fantasies.If that doesn't scare you, read his post (with comments) about the 14 Characteristics of Fascism.
The purpose of language is to communicate about reality. But what if it is not communicating reality, but fantasy? Somehow, these people are "successful" in communicating to one another (they all know exactly what the others are talking about, while you or I would say, "wwwhhhhaaaat?), and are even perversely emotionally "nourished" by the communication. It is a relief to them that others share the same fantasy--it satisfies them, fills some kind of need. But it is not a need for truth. It's like an anxious group of primitives who invent a spurious cure for a disease they don't understand.
