Well, has he been proven wrong in his assessment of the situation thus far? I found myself supporting his side during the original debacle but also kind of wrote him off as a bit of a crank because he went on a sort of national tour about this supposed problem. Today, though? It's pretty damn clear he was calling it correctly. See the ACA5 vote in California today, for a very timely example.
It's true that he got a lot of attention after he appeared on FOX, but there's more to the story. You can read about it (and many other examples of cancel culture) in the controversial book "The Coddling of the American Mind": https://www.thecoddling.com/
