otaku vs nerd

im sick of people saying im otaku. I insist i am just a anime game nerd but they insist im otaku.help me prove this to them.

what are the differences between otaku and nerd when both are into anime and games. please explain why you think soo.

The United States can enter a school without an examination up to a high school can't it?

So a school career complex is not.

and Why they enter university?

And HENTAI = abnormal a pervert

SO please do not call the adult game the hentai game

erotic isn't HENTAI
