"It seems self-evident that all speech criticizing government rulers and challenging current beliefs may be dangerous to the status quo. With full knowledge of this danger, the Framers rested our First Amendment on the premise that the slightest suppression of thought, speech, press, or public assembly is still more dangerous. This means that individuals are guaranteed an undiluted and unequivocal right to express themselves on questions of current public interest. It means that Americans discuss such questions as of right and not on sufferance of legislatures, courts or any other governmental agencies. It means that courts are without power to appraise and penalize utterances upon their notion that these utterances are dangerous. In my view, this uncompromising interpretation of the Bill of Rights is the one that must prevail if its freedoms are to be saved. Tyrannical totalitarian governments cannot safely allow their people to speak with complete freedom. I believe with the Framers that our free Government can."
