I'm not even talking exclusively about the young, but even middle-aged and up who previously were well-informed and grounded.

What happened is around 2015 news organizations were majority democrat (approx 2/3rds), Trump got nominated and elected, and because he broke their minds they fired / me too / forced out any conservative until they are now less than 5% even with closet conservatives.

Extreme example is Tom Ashbrook. Everybody lauded On Point for nearly twenty years, but a year after Trump he got me too'd, an independent investigation totally exonerated him, but WBUR/NPR fired him anyway because they didn't want to work with even a conservative-leaning person like him. Now NPR has zero people you could even suspect are closet conservatives.

There's no dissenting voices in their newsrooms and their audience hasn't figured that out.
