The problem with this assertion is that most sites, aggregators like this one, and mainstream media sites, publish as news what in former years was considered to be opinion. For example, Editorials are peoples’ opinions, yet they are presented as news articles. Almost 100% of what is on CNN, FOX, and other “news” sites are actually opinion shows. The anchor sits there and runs a clip of some video and then adds his\her own commentary. About the only thing that is real news in these programs is when they have someone like Trump that they are interviewing, and even in those cases they usually pick and choose what is presented, without context, with the intent of swaying opinions in a certain direction.
My awareness of this occurred when the Today Show played the 911 recording from the Trayvon Martin \ George Zimmerman confrontation. Seemed believable when it first came out but about two weeks later the police department released the full recording and you could see (hear) that NBC manipulated the context of the recording to show George Zimmerman as racially motivated - he wasn’t. He was responding to a direct question from the 911 operator about the appearance of the suspicious individual he was calling about. Clearly, pushing an agenda and not the truth.
I asked my father, who is 30 years older than me, when he first realized that the “news” was just propaganda that was being pushed by the news organizations. He said he realized it when he watched the OJ Simpson trial every day for the entire length of the trial. He said that anyone who watched it would come to the conclusion that there was CERTAINLY reasonable doubt as to his guilt - which meant he couldn’t be punished. Yet the media portrayed it as if every finding was that he was guilty, and it started from day one of the televised trial so it led him to believe there was an agenda being pushed.
My dad made it crystal clear to me that the “news” was just leftist propaganda as far back as Walter Cronkite....that was when I was a kid in the late 70s and early 80s. He knew Dan Rather was such a hack that if he ever saw him on the screen, he would loudly proclaim “Get that Asshole off”....much to my mother’s chagrin at hearing cursing. LOL!
Add up the ‘might’, ‘could’, should, maybe, possibly and ‘studies have shown’, plus other fuzzy words to see the percentage of editorializing going on.
