I've been flamed, spammed, cursed at, and even sent a virus via Eメール just because I stated in a コメント on YouTube that I like watching ヘタリア with subs.
I personally don't have anything against FUNimation または 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 アニメ because whenever an アニメ gets released into the USA, there's always the need to either subtitle it または dub the アニメ for people to understand it better.
Fandom can't avoid it, but can't あなた people at least try to CONTROL it??
