What would the psychology be of a Disney adult who goes to a Disney forum and diagnoses the psychology of people? Asking for a friend?
Honestly you are taking this way too seriously- Joe Rohde has posted wonderful thoughts on how theme parks become a stand in for “sacred places” that are outside the world of change.
Almost, if not all, of us agree the current rivers at DL is better. That was a significant change but it was for the better.
There is change and there is destruction. Muppets and Rivers and Fountain of Nations are all destruction for no good reason in my book.
