Here is wikipedia's definition of mainstream media:
Mainstream media (MSM) is a term and abbreviation used to refer collectively to the various large mass news media that influence many people, and both reflect and shape prevailing currents of thought. The term is used to contrast with alternative media.
So having said that, of course YAX thinks Fox News is fake news. YAX is a sheep. He doesn't understand alternative media. Fox News has always been clear that they report a conservative view. THAT DOESN'T MAKE THEM FAKE NEWS.
Fake news is when CNN puts a liberal spin on their journalism but still call themselves as non-partisan. That is FAKE NEWS.
