H. L. Mencken (1880-1956)

The most dangerous man, to any government, is the man who is able to think things out for himself without regard to the prevailing superstitions and taboos. Almost inevitable he comes to the conclusion that the government he lives under is dishonest, insane and intolerable, and so, if he is romantic, he tries to change it. An even if he is not romantic personally he is apt to spread discontent among those who are.
