Some of the best art, in all mediums, is made as protest against a backwards, conformist society.
Occasionally a good show upholds Japanese values such as pacifism, determination, or environmentalism. But even when they do so they have Japanese playing the villain, Japanese failing to live up to ideology, main characters enduring the hatred of the masses. Miyazaki's a fucking communist, and he still goes lighter on Japan than most shoujo writers I've seen.
tl;dr mangaka and otaku hate Japan even more than you do so hating them for it is moronic racism.
