Justice Jackson, characteristically eloquent:
"Those who begin coercive elimination of dissent soon find themselves exterminating dissenters. Compulsory unification of opinion achieves only the unanimity of the graveyard. The First Amendment to our Constitution was designed to avoid these ends by avoiding these beginnings. There is no mysticism in the American concept of the State or of the nature or origin of its authority."
from the Supreme Court in West Virginia State Board of Education v. Barnette
