Though Japan is the motherland for all Otaku's, arguing who has the biggest Otaku is like when you are 6 and on the playground saying things like my dad can beat up your dad, ect. It maters not on your nationality but your passion for anime, figurines, hentai, and manga.

Why is it narrowed just to America vs Japan? There's a lot of other countries who also enjoy anime.
And not everyone in America are weeabos, unless you're willing to include yourself with that generalization, Illumi.
Mostly weeabos are kids who first learn about anime and get really into a mainstream anime.
Do not forget shouting things like Desu, and Kawaii at random.
