TV Tropes and tropers have a cargo cult mindset when it comes to storytelling and its conventions.
They do not understand what really goes into storytelling, or any creative endeavor for that matter. They celebrate tropes for simply existing and assume a work is good simply because it contains a lot of they tropes they recognize, not because of any actual quality or talent present in the writing.
These circlejerk pages, like the Pantheon page, is the shrine they have built for tropes. Like the island tribes that built imitation airstrips and radio equipment in the wake of WWII, they have taken these tropes, these building blocks that they have no idea how to use or what to do with, and they have put them on a pedestal, not as narrative devices, but as memes they can use to substitute for actual thoughts, emotions, and statements.
A troper writes a story by outlining a list of tropes and minor details that they like and want their story to have (The color of the hero's hair, the main girl's bust size, their underwear, whether or not any of them wear glasses, the length of a girl's socks) and expect these lashed-together heaps of tropes and character archetypes will somehow transform into a coherent narrative, and they refuse to recognize that this never happens.
This is why they wave trash like "Fallout: Equestria" around like the printed word of God Himself, because according to tropers, these fanfics have lots and lots of tropes and surely that is all a story needs, right? And then they look at actual literature by actual writers such as Hemingway, Shakespeare, and John Steinbeck and they get confused and angry. "Where is the Nakama?" They ask, furiously thumbing through their public library's copy of Of Mice and Men. "Where's the Big Bad?, The fight scenes? The comic relief character that breaks the fourth wall? Why doesn't this book have more tropes? This book fuckin' sucks!"
TV Tropes is a website of confused islanders, building straw airplanes and cutting fake landing strips hoping that they'll magically create a real airport.
