#QuestionOfTheDay: what's the most annoying fandom/hobby argument you've ever been involved with?

if you can, include the fandom, what the argument was about, and what the sides were

(involved doesn't have to mean actively arguing it, as long as you were there in some way, watching it, moderating a board, associated with the fandom, etc, although it's more interesting if it's an argument you were actually engaged in)
