That's
bullshit.
Anime is not only big in
Japan, it is
huge in many
Asian countries as well. And
porn is far from the
majority of
anime. The only reason
Americans think
porn is
prevalent in
anime is because the desire for
sexual cartoons brought them over to
America, and they do not desire
anime kid's shows, so those were not imported from
Japan (except for
Pokemom of course). There is plenty of "
clean"
anime, such as
kid's shows,
comedy, and other innocent
entertainment.
The stereotype that all anime is ultraviolent hentai is blatantly wrong. Japanese porn is very different from American porn (I have a writeup there) due to difference in culture (see foreign dialect of comedy). If you classify all anime as porn, then it is obvious that you have been actively seeking out hentai yourself, because if you really looked around for anime instead of hentai, you would see your mistake immediately.
