Explain why calling all mainstream media outlets "MSM" and equating them with each other is lazy and uninformed, and discuss the role of news media in a democracy.
The Trump fans clearly believe that great journalism means nothing but fawning approval of their glorious hero, who they seem to have confused with Jesus. They couldn't give an objective view of the news media if their lives depended on it -- and there is none more "mainstream" than Rupert Murdoch's Fox News, which they give a free pass. Even to lump all the journals and networks together as a monolithic beast called "MSM" is lazy and uninformed; the editorial differences between (e.g.) the NYT and the WSJ, the Nation mag and the National Review, Fox and PBS are obvious. Further proof that Trumpers are info-shy. 
The great journalists of the past century have come from the mainstream outlets with their extensive resources -- long before Donald Trump and his loyal flunkies, utterly ignorant of the role of the news media in a democracy, fouled the scene with their demands for submission and endless flattery.
