And we have got to fight it with something better, not try to conceal the thinking of our own people. They are part of America. And even if they think ideas that are contrary to ours, their right to say them, their right to record them, and their right to have them at places where they're accessible to others is unquestioned, or it's not America.
—Dwight David Eisenhower
