I understand what you were trying to do, but you should be aware there are many of Wikipedians, probably the majority of us, who see no difference between "articles on a fictional universe" and "good Wikipedia-worthy article."
You often bring valid points to a discussion and are a valuable editor, but that does not mean that you are always right. It also means that you do not have to be proven wrong to have an article changed from the way that you want it. If you are right the article will be changed ultimately because you were right, not because you were arguing the point.
