Crypto-Fascism

"No man is an island, entire of itself; every man is a piece of the continent, a part of the main. Any man's death diminishes me, because I am involved in mankind; and therefore never send to know for whom the bell tolls; it tolls for thee."

That is the idea that rocketed fascism and communism past similar organizations promoting a less emotional, more individualistic idea.

They are both dualisms of extreme emotion and cold rationality. They demand theories and mathematical proofs as much as they demand total happiness and belief.
