I don't want to get my news from Facebook, so I routinely ask to "see less" of almost all politics, especially regarding Trump. There's almost never anything I wouldn't have learned about by reading mainstream news.
Here's the remarkable thing - this doesn't seem to be affecting my feed at all. I get as much politics as ever. I couldn't tell you how many times I've informed Facebook not to show me Trump news, and it's still there, lots of it. I'm starting to wonder if maybe pushing the "show less" button is akin to replying to a spammer to please don't send any spam, or perhaps pushing on a button next to a crosswalk that actually doesn't do anything, but makes people less likely to jaywalk by giving them the illusion of control.
Why am I even on the site? Well, I'm on Facebook because I like hearing about the various musical, theater, and arts events any of my friends and acquaintances are involved in. I'm not delighted that Facebook essentially controls our communication with each other - there was a time this tended to happen on the open web, rather than within the walls of a corporation, but I guess that's a topic for another day.
