I don't think fake news is a useful term, it never has been. The media has been flooded with both outright fake news and more importantly missing news for years, when it was supporting the Democrat world view.
For instance, just go look at how often you can read the Russia "invaded" Ukraine or Russia "invaded" Crimea. The Russian army is huge and what's left of the Ukrainian army is made of fresh conscripts. If those events had actually happened then the Russian flag would have been waving over buildings in Kiev within 24 hours, there would have been videos of it all over the world. You can't hide an invasion of an entire country, that's not what the word means. Yet these conquered cities are mysteriously missing.
What actually happened is a civil war in Ukraine with two opposing sides from the same country who hate each other, one side trying to break away by force. The west supports west Ukraine with materials and training, Russia probably supports east Ukraine/Donbass in a similar way, although the west admitted they were doing it and Russia never did. But let's put that to one side and assume both were at it. That's not an invasion, that is at most a proxy war.
And what happened in Crimea was even simpler, they had a vote and voted to join Russia just like they did twice in the 1990's (but were ignored). Western/Ukrainian polling and journalists have visited since and didn't find any evidence that the vote was not representative of what people there actually think.
Yet fake news stories that talk of invasion, literally fake as in "reporting on things that never happened", goes largely unremarked, especially by the kinds of people who hate Trump. They usually aren't even aware how thoroughly they've been fooled.
If you want an example of how people are manipulated through missing news rather than fake news, the recent Greenwald article on a SEAL Team raid in Yemen and how CNN reported it is a good one.
So "fake news" is the kind of thing that both sides can levy at the other, with some justification, but trying to claim one side or another is smarter than the rest is not going to work. People will just tune it out, exactly as you report.
