From Matt Taibbi:

Now the script is flipped. The press mainstream has borrowed from the old Fox model and not only (as Shapiro notes) excludes dissent via the “laundering of expertise” but leads interminable crusades against an exploding list of deviationists within their own ranks. You may have thought you were solidly a progressive, but you can catch a permanent green-room ban for going against narrative on any issue, whether it’s Syria or Ukraine or Russiagate or trans issues or any of a hundred other things. This is the same losing strategy that hurt the old GOP, which logically should lead to the same losing outcome, except this is a political atmosphere where no one seems to be winning.

Here are some examples that I have collected over the past two years. Bottom line: You should now expect that Left leaning news media will preach to you, not inform you with wide-ranging perspectives, on politically contentious stories of the day. Left leaning legacy "news" outlets like to think they are much better than Fox News, but they are often engaged in the same tactics.
