It’s one of those issues that can be applied to pretty much any media fandom, but I saw it a lot among anime fans recently, and hey, I have an anime blog, so for the time being, let’s discuss it in this context.
When was the last time you heard this rant?
I’m an anime fan, so I don’t care about what happened in your LN/manga/VN! This is an anime, so it should be judged as one. It’s obvious that due to the differences of the mediums, the adaptation is going to be a bit different, so shut up about how “inaccurate” it is.
Strangely, as much as I see them, I didn’t ever see a defense against them. No one ever comes up and explains why some people keep talking about the source material. They just keep sagely nodding at the universal wisdom that was just uttered. Apparently, the entire Internet believes that such rants accurately describe fandom etiquette.
Except, of course, the people who proceed to talk about the source material anyways. Including some of those who were just sagely nodding, right until the arrival of another series, that’s source material they are the fan of, in which case, they proceed to do the same. I guess I could write it off as people being hypocrites, and intentionally offensive rabid fanboys, but following Hanlon’s razor, it’s much more likely that the source of the conflict is poor communication between two different groups with different interests, than that one group of fan is being malicious.
