To my knowledge, no proof or evidence has been put forward that any kind of "fake news" is part of a larger plot to polarize people or influence the 2016 US elections, as was often claimed by pro-Hillary supporters. The only thing I think is safe to assume is that a lot of these "fake news" click-bait sites are there to make money. I would guess they don't really care what you think, so long as you click the link and make them money via ads.

While I think there's a decent amount of the fake news stuff on Facebook, I think it's the minority of stuff out there. Unless your friends have low standards of what's real vs. fake, your feed shouldn't be overrun with fake news.

I get my news from Love Knowledge These sources have been vetted over years of exposure so they are typically of high quality, but not infallible. There are many more sources that need to be added and this is an ongoing project of trying to evaluate which ones are the most trustworthy and truthful, something that is not a simple process.
