(To be honest, I am quite skeptical about how far he is going to be able to get with his startling proposals for America, but he does have an interesting theoretical alternate take to those who advocate maintaining the mess we have today (only more of it), and say things like "can't we all just get along?", while things seem to get worse and worse between the races.) His points about Israel and Japan and their ethnic policies, and about the effects of Section-8 housing in America, and about how the ruling elite in America do not have to deal with the problems they create when they impose their "lofty ideas" only on the rest of us, were particularly potent and inciteful.
That guy does not seem to be motivated by hate against any other race of people (like the KKK, or groups like that certainly are), but more by taking a completely honest, truthful look at the way things really currently are, and how in his opinion they could be made to work much better for everybody of all races. (It kind of reminds me vaguely of an old, non-hating Merle Haggard country song, "A White Boy (Looking For A Place To Do My Thing)".)
“Are there any other resources (other videos, books, web sites etc.) of that controversial guy that you can recommend, where he argues his views in more detail about the shrinking/disappearing white culture, and what he believes that means will happen here eventually in the not-too-distant future if things don’t change?”
