Whitewashing (censorship)

To whitewash is a metaphor meaning "to gloss over or cover up vices, crimes or scandals or to exonerate by means of a perfunctory investigation or biased presentation of data".
Etymology.
The first known use of the term is from 1591 in England. Whitewash is a cheap white paint or coating of chalked lime that was used to quickly give a uniform clean appearance to a wide variety of surfaces, such as the interior of a barn.
In 1800, in the United States, the word was used in a political context, when a Philadelphia "Aurora" editorial said that "if you do not whitewash President Adams speedily, the Democrats, like swarms of flies, will bespatter him all over, and make you both as speckled as a dirty wall, and as black as the devil."
Modern usage.
In the 20th century, many dictatorships and authoritarian states, as well as democratic countries, have used whitewashing in order to glorify the results of war.
For instance, during the Soviet invasion of Czechoslovakia following the Prague Spring of 1968, the Press Group of Soviet Journalists released a collection of "facts, documents, press reports and eye-witness accounts." Western journalists promptly nicknamed it as "The White Book", both for its white cover and its attempts to whitewash the invasion by creating the impression that the Warsaw Pact countries had the right and duty to invade.
In the early 21st century, North Korean radio broadcasts claimed that the nation has abundant food supplies, yet the government received food aid from foreign states.
In the study of reputation systems by means of algorithmic game theory, whitewashing refers to the abandonment of a tarnished identity and creation of a blank one, which is more widely known in internet slang as sockpuppeting.
Some critics have accused Michelle Alexander's "The New Jim Crow" of being whitewashed due to the bias of its conceptual framework. It omits pertinent African American people and history, as well as politically radical ideas in favor of a more conventional and mainstream perspective.
Representation in other media.
Novels by George Orwell have dealt with the subject of whitewash as well. In "Animal Farm", the pig Napoleon tries to whitewash history by deleting a few characters from the minds of the other animals. This was perceived as a direct reference to the USSR under Stalin. The protagonist of his novel "Nineteen Eighty-Four", set in a totalitarian dictatorship, is employed as a routine falsifier of the historical record to ensure that it is always in keeping with the party line.
Czech writer Milan Kundera, in his novel "The Book of Laughter and Forgetting", described histories being revised with both text and photos being changed to take out unpopular dissidents or people on the wrong side of the government.
