Media redefinition
From Conservapedia
Media redefinition pertains specifically to the labels and descriptors given to individuals in news stories and which change as the public perception of a given individual shifts. Often, a racist element is involved - for example dropping or downplaying an individual's foreign heritage when said individual succeeds but emphasising it when they are disgraced, as in the case of Ben Johnson[1]
This sort of media redefinition is common among liberal media outlets but less controversial instances have been known to occur within conservative outlets such as Fox News. Examples include the suppression of the word "rich" in favour of the term "job creators", or less recently, the use of "homicide bomber" instead of "suicide bomber".
