I actually get their thinking it's just so flimsy and full of bad logic.

You take the idea that some countries are poorer and more trash filled than the rich european countries and conclude that their ethnicity is the problem. Basically just be really racist and then it makes sense. Throw in some occult imagery and greek/roman aesthetics and boom, cult.

Ted Kaczynski and Charles Manson did this sort of thing. It's not new.
