I think a lot of the problem arises when people refuse to actually have a discussion. The hardcore fandoms need to understand that just because someone is criticising something you like, doesn't mean they hate it.
I agree with this and think it's pretty spot-on in many situations. Unfortunately, most attempts at constructive discussions (at least some that I've observed online) devolve rather quickly. Thankfully, not everyone online is this way, and I believe that most of the narrow-minded ones are (overall) a minority. Unfortunately, these are the people who usually scream the loudest.
I've had the sub vs. dub discussion as well, but a more recent experience for me has to be the bashing of Yo-kai Watch within the Pokemon fandom.
