Evil Scum

"If he were allowed contact with foreigners he would discover that they are creatures similar to himself and that most of what he has been told about them is lies. The sealed world in which he lives would be broken, and the fear, hatred, and self-righteousness on which his morale depends might evaporate."
  --- Goldstein, Theory and Practice of Oligarchical Collectivism quoted in Orwell, 1984.
