Ok, regarding the term Otaku,... it is true that the term Otaku sometimes has a negative stereotype however,

Otaku (おたく/オタク?) is a Japanese term used to refer to people with obsessive interests, particularly anime, manga, and video games. In modern Japanese slang, the term otaku refers to a fan of any particular theme, topic, or hobby. definition from wikipedia

If I said I was a otaku of japanese culture i would be "most likely" catagorizing myself as someone who fits those traits based on the definition, and not negatively sterotyping myself. Otaku is not a negative term. All it means is I really like something, like anime.

So i don't see anything wrong with just the term Otaku, its just the sterotype that goes with it. What I mean is... He/She is a Otaku so all i do is watch anime all day. Thats a stereotype because its not necessarly true and has nothing to do with the definition.

Here is another example...
If i am a Technican, I fix electrical equipement. Definition.
He is a technican that does not do much work. Opinionated Fact
I am a Technican as well as my friends, so we don't do much work either. Stereotype

Hope this helps...
