NSA Dissident

A dissident, broadly defined, is a person who actively challenges an established doctrine, policy, or institution. When dissidents unite for a common cause they often affect a dissident movement.
The word has been used since 16th century in the context of religion. The noun was first used in the political sense in 1940, with the rise of such totalitarian systems as the Soviet Union.
