Which fandom started it?
The reason why I don’t mention much about any fandom directly even though I could write quite a bit about them (regardless whether I myself am or not am part of that fandom) especially about kpop related fandoms: Sone, ELF, Blackjack, VIP, B2uty, KissMe, BANA, Primadonna,A+, Shawol etc., is rather simple: Since I hope there will be less fanwars and other childish actions I want what I write to be “readable” for any fandom (though I do have a bias on korean entertainment and music). It’s not the question “which fandom started it?” or “which has to stop?” or “which is at fault?”, but how well they respect each other. Of course there will always be such people in a fandom who think they need to bash others (etc.) but it’s up to the rest of the fandom (especially the more mature persons within it) to guide those fans well (though I can understand if you don’t want to waste your time discussing those things), just don’t forget that some fans are really young (or regardless of age just immature) and therefore might need a thought-provoking impulse (—> How to be a good fan)
