Sometimes people need to be angry at their government. When the army is knowingly and deliberately irradiating a town in secret, people need to get angry. When the President is part of a conspiracy to break into the offices of his political opponents during an election, people need to get angry. When the director of national intelligence is lying to Congress about the intelligence community's violation of civil rights, people need to get angry.

If we silence conspiracy theorists, we ensure that conspiracies will never be unraveled because nobody will be allowed to bring them to light.
