There _was_ a huge wave of actually fake news during the POTUS campaign. Some stuff was clearly BS clickbait from a plethora of websites we’ve never heard of before nor since. A lot of people fell for the startling headlines and forwarded links without considering the source.
Of course, the Left is using the reality of that to impugn respectable right-leaning news sources.
Let’s not completely bash the notion of “fake news” because it does exist, outright fabricated content for deception and/or clickbait.
We could compile a list going back a century. It would be fun and educational.
