“Tolerance cannot be indiscriminate and equal with respect to the contents of expression, neither in word nor in deed; it cannot protect false words and wrong deeds which demonstrate that they contradict and counteract the possibilities of liberation. Such indiscriminate tolerance is justified in harmless debates, in conversation, in academic discussion; it is indispensable in the scientific enterprise, in private religion. But society cannot be indiscriminate where the pacification of existence, where freedom and happiness themselves are at stake: here, certain things cannot be said, certain ideas cannot be expressed, certain policies cannot be proposed, certain behavior cannot be permitted without making tolerance an instrument for the continuation of servitude.” – Herbert Marcuse, “Repressive Tolerance”
