Hmmm, I think a better word than "fantasy" here is "dystopia." Robertson is painting a bleak picture of a world where without moral authority, like the (much longer) bleak depiction of say, Fahrenheit 451 of a world without intellectual freedoms. Again, the natural reaction to reading Fahrenheit 451 or hearing Robertson isn't gleeful cackling, but shocked horror. "Something ain't right."
