The problem with mainstream media reporting is context.  When they report that Trump supported the war in Iraq, the context was a flippant comment that he didn't think about it or really cared.  

Another is when the news reports that China is taking green energy seriously, when in fact they are firing up 2 coal fired power plants a week according to Greenpeace.  Their green energy plan is designed for export.  

Or we are producing more greenhouse gas than ever before.  The fact is our population has almost doubled over the past 50 years and of course we produce more greenhouse gases. There is also the fact Asians are eating beef, which they never ate before and cattle produce methane.  Environmentalists rarely talk about cattle and methane.

If the reporting is accurate but the context is wrong, then it's fake news and that's why the media has a credibility problem.
