I would say some of the things that he premised on was true. But the idea he developed base on those things are nuts. it's not how he communicated them, it's just what it is.
(example not necessarily from Alex Jones, but just e.g)
US flag furled up on the moon (correct) -> like the wind blew on it (visual observation) -> it means the wind must have blown on it (fallacy) -> we never went to the moon.
Jet fuel cannot melt steel (maybe? correct) -> Therefore the fire it had on the world trade center cannot cause structural failure (does your chocolate not soften before it melts?) -> US did 911.
The premise can be true, the idea can still be bs.
There is a ~40min video in my profile that is just footage from the day and mainstream technical talks afterwards.
That's not an ordinary difference of political opinion. One side or the other is engaging in conspiracy-theory thinking, at a vast level. (Or, I suppose, both.) I don't just mean that they're talking about a conspiracy, but applying all the hallmarks of paranoia, shifting goalposts, and bad faith that mark conspiracy theorists.
And that's just one example. It applies down the line, of many issues. This is the one that perhaps illustrates it best, but it's not mere partisanship. It's people needing to be "brought back to earth", as you said, but at a level involving many millions of people.
That's the kind of talk that leads to re-education camps.
I'm also not proposing solutions. I'm sure there are many who would propose re-education camps -- that, too, is an indicator of the magnitude of the problem.
I'm actually quite short on ideas for solving it.
