Alexei Maxim Russell Quote

Whereas an Otaku is a true connoisseur of the culture, showing the same reverence and respectful distance which any true expert shows to their chosen field of expertise, the Weeaboo is like a socially awkward adolescent, ineptly trying to gain the social acceptance of Japanese people — because their unfortunate mental disorder has caused them to believe they are, in fact, Japanese.
