I agree, although I'm not sure if there's really that much disagreement on the actual facts, at least as far as the basic facts. But there seems to be some nuances and variations of perceptions. It's like we're all looking at the same thing, but some people see it as something different.
But I also think we've found ourselves at cross purposes to a large extent. Some factions just have different goals and aspirations. The whole slogan of "Make America Great Again" hearkens to an earlier America, a period which is often idealized in many people's minds. Whatever the current news might be, whether it's "real news" or "fake news," it doesn't really seem to shake that image in people's minds.
I remember they used to call it "Middle Class Morality," but then there was Nixon's "Silent Majority" and Reagan's "Moral Majority." What we're dealing with here is a quasi-religious ideal which has been going on for generations and runs pretty deep within the fabric of the country. I don't think they really constitute a "majority," and it's also true that at least an equal or greater number of Americans has strongly opposed them over the same period of time.
It's a political rift which has gone on for a long time, although there have been long periods where it's mostly been restrained. For whatever reason (and I'm not sure how it happened), Trump's rise appears to be symbolic of a lack of restraint. He himself is the embodiment of a lack of restraint, yet he's still symbolic of the deep, dark underbelly of what America was in earlier times, back when we were "great."
In other words, there are a lot of people who seem to believe that Trump will lead America into some kind of "Leave it to Beaver" world...or maybe "Mayberry RFD." That's the America they want, and they don't really want to hear from people who say they can't have it. Trump says otherwise, and that's why they believe Trump.
