As Hayao Miyazaki once said, "Those who identify as 'otaku,' they sicken me deeply." Otaku are a problem group. Most of them are asocial or antisocial, delusional, mentally inept, rash, and all around deranged. Many of them have racy sexual desires, fantasizing about rape, incest, pedophilia, and other such illegal perversions. If you can think of anything bad about a certain group of people, otaku likely fit that quality, and more.
