Before the age of Political Correctness when John Langdon Down's was a physician, Down's Syndrome, the genetic condition that he was named after was called Idiot Mongolism.

Often mistakenly attributed to Lenin, Stalin or Marx, the term was first used by US newspapers in 1948 and has little documented usage within the Soviet Union, meaning a third party who spreads propaganda or disinformation, usually unintentionally or without fully understanding the cause they're proselytizing for. Originally used during the cold war to refer to Western communist sympathisers, or those susceptible to communist propaganda, the term could be used today to refer to those spreading anti-vaccine misinformation echoed or amplified by Russian intelligence, or ,or Trump supporters acting on foreign-spread conspiracy theories about pizzas and child molesters. In any case, the person spreading the disinformation uses someone susceptable to the disinformation in order to spread it further
This useful idiot read online that Hilary Clinton is selling kids through this pizza place and now he's going down there to shoot it up.
