Your survey is using a highly biased population sample (i.e. people who took the time to make an account on OriginalTrilogy.com) and therefore the responses do not represent the “average Star Wars fan”. The people here (including myself) represent a distinct cohort of Star Wars fans with opinions that skew towards rejection of OT revisionism, dislike of the Prequels and Special Editions, and distrust of George Lucas as a creator. The responses you get will reflect the average opinions of this particular cohort of fans, not the average Star Wars fan.
I suspect the average Star Wars fan has very different opinions about Star Wars than the average member of this forum. I also suspect the average or median age of the people that participate in this forum is a bit higher than the average age within the “general population” of Star Wars fans. In fact, an old-school Internet forum like this (as opposed to a modern social media platform) most likely selects for relatively older people.
