In a dictatorship, the only way to get rid of it is by starting violence.  Violence undermines dictatorships when the people of a totalitarianism country want to change their governmental ways.  This is the same for propaganda, it undermines democracy.  Propaganda is bad for democracy and will be the demise of it at some point if we keep failing to recognize it.
