A JournalPoser is an opinion writer posing as an objective journalist. The JournalPoser spins the news in an idealogical direction to suit his or her own views and purposes, without disclosing that the bias is built in.
Ethnic-oriented news journals and sexual orientation reporters are often JournalPosers, especially when they do not disclose their bias.
(Journalists such as Rachel Maddow are not JournalPosers because it is clear that opinion and interpretation are the force behind the content.)
The San Francisco Bay Guardian assigned a JournalPoser to the 2012 mayoral election in favor of gay candidate Bevan Dufty. Their coverage was over-whelmingly positive regarding Dufty (who eventually lost by a landslide). When key reporter Joe A.W. Fitzgerald was presented with negative news about Dufty, he responded 'Ouch' and would not engage. The strong bias had not been disclosed to SFBG readers.
