Since he was a nazi, I’m glad you and your friend dodged that bullet and he was ejected from her life. That said, nothing about what he was telling you strikes me as inherently nazi or fascist. Was he actually trying to convert you to ancient Christian gnosticism (which I think would be weird even for a nazi)? Talking about the demiurge is not a nazi dogwhistle or tactic. I mean Matt Christman is well known for expounding on the demiurge! The demiurge is fairly frequently brought up here on hexbear. As an interesting coincidence, the last TrueAnon episode discussed the demiurge.

Later revelations about this person aside, from everything you’ve said about the interaction itself, it just sounds like an interesting conversation you could have had just as easily with a leftist.
