I agree with your premise.
You refer to media 3 different ways, Old Media, mainstream media and center-left media.
(really) Old Media (maybe when Rodney King went down media) weren’t as focused on the simplistic divisions you mention (victims, oppressors, enlightened).
The dumbing down of “media thought” and brain dead categorization and reduction into isms, racism, ageism, feminism, isms and more isms, seems to me a reasonably recent phenomenon.
And directly related to the idiot-thought dominating our public schools and those “teaching” our children, including those teaching our print journalists.
A long way of saying that so much complete and utter crap makes it into print today, it’s embarrassing.
