Not that we want to single out anime fans, but they serve as a good example for this. It's not hard to find young anime fans dreaming of living in Japan, because if anime gets them ostracized as nerds in the West, why, moving to Japan would be like going home! It's all anime over there, all the time. And it's just assumed that Japan will be thrilled to have them. After all, here is a Westerner who gets Japan! Welcome, American!
"It is so refreshing to meet a grown man who truly appreciates our children's cartoons."
But if these people do move to Japan, they quickly figure out that as much s**t as they may have gotten for anime fandom in the USA, it's much worse there. To the average Japanese person, the words "adult anime fan," or "otaku," conjure less admiration and more an image of someone who sleeps between a hentai-print body pillow and the decomposing bodies of his parents. When the tsunami caused the cancellation of an anime convention, the Governor of Tokyo said they "deserved it" (he's a big advocate of new laws that restrict the sale of anime to young people). He was then re-elected.
"I hope they're pulled down headfirst by their cosplay wigs."
