The show. In the instances I questioned I pointed out where the show disproves the claims made. In the cases where it was less about the show and individual interpretation the poster I questioned proved I was correct with their own words while still arguing against me. Galadriel being more powerful then her troops is not a fundamental flaw in the narrative. She is the main character and her troops are not important. It didn't need a long drawn out fight scene showcasing the individual accomplishments of each elf under her command. It was one ice troll that ambushed the elves having gone unnoticed by even Galadriel.
This is not low level fan fiction and if you've actually seen such a thing you would not state such and be expected to be taken seriously. Such silly statements and exaggerations undermine anything legitimate you might say.
