Fascism creates confusion through “facts”. It relies on junk science, revisionism, the elimination of cultural records/treasures and obfuscations to create its case and gain acceptance. Fascism can also combine Marxist critiques of capitalism or faith based critics of the same to re-define middle class perceptions of democracy and to force its issues, confuse logic and create majority consensus between targeted groups. This is also referred to as creating a state of cognitive dissonance, the mental state in which human beings are most easily manipulated.
Fascism is an extreme measure taken by the middle classes to forestall lower-working class revolution; it thrives on the weakness of the middle classes. It accomplishes this by embracing the middle class love of the status-quo, its complacency and its fears of: a) generating a united struggle within the working class, b) revolution and c) losing its own power and position within society.
In more simplistic terms the people currently in control fear that if they allow equal rights and equal consideration to those being oppressed, they will become oppressed and lose everything.
