Communism
From Memory Alpha, the free Star Trek reference
Communism is a political and economic ideal and philosophy that was embraced by several Earth nations in the 20th and 21st centuries. Nations that embraced it included the Soviet Union and China. Slang terms for a person who followed this ideal, better known as a communist, included "pinko", "red" and "commie." It was the clash between communism and capitalism that drove the Earth Cold War.
In 1953, Douglas Pabst insinuated that Herbert Rossoff was a proponent of communism. (DS9: "Far Beyond the Stars")
