I am currently getting into the Slender Manmythos, an online phenomenon that has grown into a full-blown urban myth. It began in 2009 as an online photoshop competition to transform ordinary photos into fake paranormal photos. A character called Victor Surge made two photos of an unidentified man standing near children. He was very tall and had strange, tentacle like arms. Victor Surge added a detailed, thumbnail back story about a library fire. The legend grew from this point:
Slender Man (a.k.a Slenderman) is a mythical creature often depicted as a tall, thin figure wearing a black suit and a blank face. According to the legend, he can stretch or shorten his arms at will and has tentacle-like appendages protruding from his back. Depending on the interpretations of the myth, the creature can cause memory loss, insomnia, paranoia, coughing fits (nicknamed “slendersickness”), photograph/video distortions and can teleport at will.

Fascism makes no logical sense. It is a scavenger philosophy. Its class base, the middle-class, has no consistent point of view within capitalism. But fascism makes illogical sense.
It coheres into a movement on the basis of mythos. A note: the German word for uncanny is unheimlich, which in turn derives from heimlich. Heimlich has two meanings, one of which means homely, comfortable, the other secret or concealed. Fascist movements at their core are often based around esoteric, concealed knowledge.
But fascist movements are stimulated by a return of the repressed, the unheimlich. In 1930s Germany it was a combination of economic depression and the Russian Revolution: amalgamated to produce the myth of a global Jewish conspiracy, a repulsive, lunatic theory, but it founded the Third Reich.

Fear (and fascination - the enemy is always stronger and more vital) is an adrenaline shot for fascism, which can make it tremendously energetic. The repressed element, the working class in its most fearsome, elemental form, had erupted. The ruling class fosters fascist ideas so if at any stage it doubts itself, it has this paranoid, demented force in reserve.
