Oh god, you have no idea. The Silent Hill fandom is probably one of the most drama-saturated on the internet. Since it's so deep-rooted in theorizing, you get tons of crazies and elitists.
That's why the whole "J-rock" fandom isn't so bad. Yeah, there can be absolutely batshit fans and really infamous characters, but it tends to be way less crazy because it's usually deep-rooted in sexuality and not total mental instability.
