It's a backlash we've seen in recent years -- overenthusiastic anime fans ("weeaboos") have been held up as evidence that anime/manga fans are all maladjusted mouthbreathers. The truth is, EVERY fandom has socially awkward people, many of whom are perfectly lovely individuals once they've had a chance to grow. Demonizing anime/manga is just the new thing that insecure nerds do to build themselves up ("at least I'm not as bad as THOSE LAME ANIME PEOPLE").
