In a lot of ways, I really don't blame the current political climate, because the US has seen way worse (read up on the US 1800 Presidential Election). I actually blame poor applications of algorithms to what folks view. The bias caused not only by the beliefs of the person training the box and the professional poster's ability to learn how to manipulate the results (the next generation of SEO) has increasingly made twitter and facebook painful to use. Add a large bit of tribalism that is baked right into humanity and you have a lot of fun. Further strain through the idea that a lot of companies won't even just let the users pick accounts they always want to see regardless of the beliefs of the provider, and you get a added bit of helpless feeling in the populace.
Which makes writing a pain. I've seen some folks take offense at grant applications that are basically some of the most dry reading you will find. It once was a don't use this era's forbidden words (e.g. the word "empower" had a very strange evolution in grants). Now its memes.
Regardless, the term 'fake news' is IMHO itself kinda fake news.
No, both sides love using the term about anything the other side says.
