I looked up the author of Duke's little communist list:
He was a wacko Mormon & anti-communist conservative,
.... who was rejected by LDS for being too friendly with nazi's
the constitutional scholar Jack Rakove, of Stanford University, inspected Skousenís books and seminars and pronounced them "a joke that no self-respecting scholar would think is worth a warm pitcher of spit."
A 1971 review in the Mormon journal Dialogue also accused Skousen of "inventing fantastic ideas and making inferences that go far beyond the bounds of honest commentary," and also of promoting concepts that were "perilously close" to Nazism.
