They say Japanese were originally Chinese.
Some traitor betrayed an emperor saying, he'd find a medicine for immorality sailed away with 100 children and never came back. The place they ended up in was supposedly Japan. Then in Ming dynatsy, Japanese students came as "exchange students" and brought our culture back to Japan. It became their culture. And now, something so recent, kimono, shinto, even japanese archetecture is a focus of fascination, instead of their point of origin, China. Japan denies it of course, but we can find statues of the traitor, who is now being worshipped as the great founder, in Japan. Well that happened some thousand years ago, so non-azns prolly wouldn't know of such a history. But that's just it, a story, who really knows what happened some k years ago? The facts prove the assumptions. Kinda like quantum mechanics (but that's beyond the point).
Personally I believe it. So I understand where you're coming from as well.
Also this is a bit of irony, we are so bitter towards them, but we like their ways. D;
According to what you said tho... shouldn't it be non-anime artists who are feeling insecure and wish to shun us? x.x
