Noam Chomsky on thought control

The beauty of the democratic systems of thought control
as contrasted with their clumsy totalitarian counterparts,
is that they operate by subtly establishing on a voluntary basis,
aided by the force of nationalism and media control by substantial interests,
presuppositions that set the limits of debate
rather than by imposing beliefs with a bludgeon.

Then let the debate rage,
the more lively and vigorous it is,
the better the propaganda system is served…

Those who do not accept the fundamental principles of state propaganda,
are simply excluded from the debate.
(or if noticed, dismissed as "emotional," "irresponsible," etc…)
