Pinko is a critical term coined in America in 1925, originally to describe a person regarded as being sympathetic to communism, though not necessarily a Communist Party member. It has since been used as a derogatory term for someone who is (it is claimed) more socialistic than otherwise thought. Examples could be; someone on the political right who is seen as being 'overly' socialistic on particular matters, or someone on the political left who is (it is claimed) further to the left than he or she is normally known to be.
The term has its origins in the notion that pink is a lighter shade of red, a color associated with communism. Thus pink could describe a "lighter form of communism", purportedly promoted by supporters of socialism who were not themselves actual or "card carrying" communists. The term pinko has a pejorative sense, whereas 'pink' in this definition can be used in a purely descriptive sense, such as in the term pink tide.
The word pinko was coined by Time magazine in 1925 as a variant on the noun and adjective pink, which had been used along with parlor pink since the beginning of the 20th century to refer to those of leftish sympathies, usually with an implication of "effeteness". In the 1920s, for example, a Wall Street Journal editorial described supporters of the progressive politician Robert La Follette as “visionaries, ne’er do wells, parlor pinks, reds, hyphenates [Americans with divided allegiance], soft handed agriculturalists and working men who have never seen a shovel.”
Pinko and pinky were widely used during the Cold War to label individuals accused of supporting the Soviet Union, including many supporters of ex-vice president Henry Wallace's 1948 U.S. presidential campaign with the Progressive Party. The word was predominantly used in the United States, where opposition to Communism grew strong among the population, especially during the McCarthy era. It was also in common use in South Africa during the apartheid era. In his two presidential campaigns, Alabama governor George Wallace often railed at "the left-wing pinko press" and at "pseudo-pinko-intellectuals."
Some of the most infamous uses of the term pink came during future president Richard Nixon's 1950 Senate campaign against Helen Gahagan Douglas: "She's pink right down to her underwear!" — a play on the fact that, at the time, pink was the usual color of women's undergarments. Nixon regularly referred to her as "the Pink Lady", and his campaign distributed political flyers printed on sheets of pink paper.
Popular culture 
One of the most famous uses of the term in popular culture was the ironic use by Charlie Daniels in his breakthrough 1972 hit "Uneasy Rider." The dope-running hippie narrator is stuck with a flat tire in Jackson, Mississippi. Attempting to avoid a beatdown by the locals, he attempts to deflect attention to one of the locals by accusing him of being "a friend of them long haired, hippie-type, pinko fags" sent by the FBI to infiltrate the Ku Klux Klan.
Archie Bunker, the patriarch of the Bunker family in the 1970s sitcom All in the Family often derisively used the term 'pinko' when referring to his liberal son-in-law Michael "Meathead" Stivic or Michael's friends.
Tabloid-TV talk show host Morton Downey Jr. was famous for using the term to berate nearly anyone who disagreed with him.
The term was used repeatedly on the television series John Safran vs God when Safran is referring to his target demographic. Safran is likely to have intentionally referenced Daniels' "Uneasy Rider", and notably Safran had on a previous episode infiltrated the Ku Klux Klan.

He also uses the term once or twice in the 'Handbook' feature of the game, which teaches the player about weapons, vehicles, etc.
