"Maybe their problem is that they've confused scientific theory/the scientific method with fan speculation? That would explain a lot. Like, they saw how scientists use facts taken from the world around them to prove or disprove their theories of How Shit Works and thought they could do the same with fandom. Unfortunately for them, fandom is less like biology and more like theology. Or rather, theology in a world where the deities who hand down sacred texts are unarguably real, everyone knows they're real, and they exist in physical form within the mortal world, which they directly interact with on a daily basis. You can argue your interpretation all you want, but if your deity tells you you're wrong, then you're wrong. No if's, and's or but's."
