Do you think it was caused by the completely arrogant claims from Lucas claiming that he planned everything for decades and had a "vision" coupled with the unhealthy cult-leader worship that TFN people had for him? It would make sense I guess since I don't think there were any "true vision" speeches back when Jedi came out, making it OK for people to dislike it.

Yeah, that's what I think happened. Lucas became a messiah in their minds, and when confronted with evidence to the contrary, they became pseudo-religious zealots, treating each and every person who didn't buy into Lucas' vision like heretics worthy only of being burned at the stake.
