   I think that's a good point

   If you tell a lie big enough and keep repeating it, people will   
   eventually come to believe it. The lie can be maintained only for such   
   time as the State can shield the people from the political, economic   
   and/or military consequences of the lie. It thus becomes vitally   
   important for the State to use all of its powers to repress dissent, for   
   the truth is the mortal enemy of the lie, and thus by extension, the   
   truth is the greatest enemy of the State.
