The Grayzone is a webshite founded by Max Blumenthal, a contributor to RT. It purports itself to be “a news and politics website dedicated to original investigative journalism on war and empire[2], but it mostly promotes Assadist, Russian, Venezuelan, and Chinese propaganda. It is known for using ad hominem attacks by calling critics neocon shills,[3] or Mccarthyites.[4]
