"The Lefty Liberal MSM created the current theme of Fake News and it blew up right in their face when so many Liberal news sites have been caught making fake news story after fake news story."

Let us deconstruct the language used by Trump supporters to justify his juvenile tirades. 

"Lefty Liberal MSM" - Lefty and Liberal are interchangeable terms referring to anyone with operational gray matter and a conscience. MSM is a catch-all term to denigrate the profession of journalism, because journalism reveals truths Trump supporters find inconvenient. 

"created the current theme of Fake News" - This fragment implies that the concept of Fake News is an invention used to wrongly discredit Trump. In keeping with the general mindset of all things Trump, it is a flat out lie.

" it blew up right in their face when so many Liberal news sites have been caught making fake news story after fake news story." - And here's the  Trumpian practice of accusing your opponents of your own sin. Sad.
