One last addition. The case of the NYT reporter Sheryl Stolberg, is indicative of the stuff I am trying to outline and interested in terms of media/social media/political speech/ideology and Trump dynamics. 

Stolberg was actually on the scene. She tweeted how "The hard left seemed as hate-filled as alt-right. I saw club-wielding "antifa" beating white nationalists being led out of the park"...She also questioned the police response and management.

This led almost immediately to a twitter mob and moral outrage (see link) from left forcing Stolberg to "correct her own eyewitness account" to "Rethinking this. Should have said violent, not hate-filled. They were standing up to hate"...

I think it is impossible to look at coverage of Trump (but "right" politics/politicians in general) and media bias without critically examining these dynamics. Maybe I am too lenient on Trump, but this is exactly the stuff he exposes. The media has some serious questions to ask of themselves as well!
