Stop us when this becomes familiar:
"The receptivity of the great masses is very limited, their intelligence is small, but their power of forgetting is enormous.
In consequence of these facts, all effective propaganda must be limited to a very few points and must harp on these in slogans until the last member of the public understands what you want him to understand by your slogan.
As soon as you sacrifice this slogan and try to be many-sided, the effect will piddle away, for the crowd can neither digest nor retain the material offered.
In this way the result is weakened and in the end entirely cancelled out."Source: Chapter 6, "War Propaganda" of Adolf Hilter's 1926 "Mein Kampf"
We need to rid ourselves of the single man view of history. If it wasn't Hitler, make no mistake it would have been someone else to head that particular parade. Society has a velocity and trajectory that is not the will of one man, but the confluence of a million tiny pushes from everywhere. Politicians and powerful people are just a special breed that can diagnose this and position themselves in front. This is why individualism is far superior as a check on such collectivist madness.
But of course, this can't happen in America, or can it?
