I've been flamed, spammed, cursed at, and even sent a virus via email just because I stated in a commento on YouTube that I like watching Hetalia Axis Powers - Incapacitalia with subs.
I personally don't have anything against FUNimation o anything like that. In fact, I sort of like Sealand's dub voice.
I know it's impossible to avoid a sub vs. dub war in ANY Anime because whenever an Anime gets released into the USA, there's always the need to either subtitle it o dub the Anime for people to understand it better.
Fandom can't avoid it, but can't te people at least try to CONTROL it??
