Yes, Nigel, it's profoundly disturbing. To add to it, the similarities between Bannon's views and those of Anders Breivik (the Norwegian white supremicist mass murderer) are pretty hard to overlook.
Breivik's dystopian novel of choice was The Turner Diaries, also beloved of Timothy McVeigh, the Oklahoma City bomber. Creepily enough, Breivik timed his slaughter to memorialize the halting of the Ottomans at Constantinople in the 15th century, an event mentioned in the French novel as well.
