Of course everything has a bias, but these are some of the biased organizations that I'm tracking things on.
Facebook is completely non-partisan and has no biases or agendas, right? LOL. History proves that FactCheck.org was partisan and bias, but since their acquisition by Facebook, it seems that they won't have even the false front of being a "J-School", which are all partisan, it's just Zuckerberg's sock-puppet.
David Remnick took over as Editor and they became the cheap partisan low-quality mock-worthy rag that they are today. This details just a small portion of that.
Propagandaministerium of America. They exist to take things out of context, lie, distort, and feel that any means to their ends (of furthering the power of government over the people) is justified. At least based on their actions. If you can't look at anything they post, and find at least 10 things wrong with it, then you're not qualified to have a discussion.
Politico started when left-of-center John F. Harris, and the slightly less left-of-center Jim VandeHei (who left to found Axios in disgust, and penned a FU I'm outta here letter), got funding for a DC tabloid journalism (rumor mongering) on the DC set. Sort of what HuffingtonPost was to Hollywood, but only for DC, if HuffPo had even lower ethical and journalistic standards. The point isn't that I dislike Politico -- its looser quality controls allows for some people to get a voice that they wouldn't have elsewhere. So to me, it's like reddit or twitchy -- sure most articles are full of shit, but they allow both sides turds, and you can find some treasures in the sewage, if you are willing to wade long enough.
