pretty funny stuff.
i would add a few other categories to that, but i won't. hehehehe.
that said, i have no interest in anime and manga.
i don't hate it. but it just doesn't grab my attention.
if there's anything i'm most interested in since moving here, has probably been the history. but there are many fascinating things japan has to offer. manga/anime makes up a small percentage of it -- but the fans are, well, obsessive to say the least.
japanese manners
traditional art
modern art
architecture
business style
politics (i suppose some people are interested in them here. lol.)
comedy
music
and believe it or not, some people have little interest in japan outside of learning the language.
actually, the majority of expats i know here who are interested in anime/manga are the norm, i think. i only know 1 (maybe 2) foreign otaku.
so whatever your reason for studying, just keep on with it and don't worry about what other people think. there is no gaijin elite that controls what constitutes a valid reason for studying, especially not otaku, who are generally disliked by the non-otaku majority. (btw - i'm not ripping on otaku, since i hang out with quite a few japanese otaku, but the fact of the matter is, they're a subculture and one that a lot of mainstream japanese disdain.)
