Shub-Niggurath, Please
It occurs to me you could say the same about lots of elements of the Christian Right as well. Culturally medieval - literally so with the Qanon eschatology - but using modern technology to spread the madness. Off topic so carry on.
Plus, you know, the Nazis! Bunch of Odin-worshippers and rune-fetishists setting out to conquer the world in cutting-edge tanks, subs and aircraft. Not such a different vibe from ISIS's apparently pretty slick social media presence.
