The problem with the propaganda period is always that the voices of reason are shouted down by the voices of the manipulated masses.

"There was no point in seeking to convert the intellectuals. For intellectuals would never be converted and would anyway always yield to the stronger, and this will always be "the man in the street." Arguments must therefore be crude, clear and forcible, and appeal to emotions and instincts, not the intellect. Truth was unimportant and entirely subordinate to tactics and psychology." ~ Joseph Goebbels
