The United States can ... be proud that it has institutions and a structure that permit its citizens to express honest dissent, even though those who do so may be maligned by the highest official in the land.
Those who begin coercive elimination of dissent soon find themselves exterminating dissenters. Compulsory unification of opinion achieves only the unanimity of the graveyard.
Mere unorthodoxy or dissent from the prevailing mores is not to be condemned. The absence of such voices would be a symptom of grave illness in our society.
