Hentai = Western term for sexualised anime/manga.

In linguistic terms we would say that the term has been "bleached" - it has lost any pejorative meaning. Hentai to the Westerner means animated or drawn characters engaging in sexual activity, not "pervert" as it does in Japanese.

Stop being so touchy.

God damn I hate when people get on their high horse about these things. "Don't call it hentai, call it eronime. Don't call me otaku, call me fanboy." They're loan words from another language and as such their meanings undergo transmogrification to adapt to our needs.

Jesus fucking Christ.
