And this is why rational arguments lose.
“All propaganda must be popular and its intellectual level must be adjusted to the most limited intelligence among those it is addressed to…. effective propaganda must be limited to a very few points and must harp on these in slogans… 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.” -Mein Kamph, Chap. 6.
