I think you're taking offense voluntarily just because you want to.

This is an alternate universe. There's no guarantee, just because each country in this reality has similarities to real countries, that any of them are meant to be a reflection of the real countries in the real world.

In addition, this is a work of fiction. I think it's ironic someone else made a discussion asking why the creators had to make that disclaimer all the time. Obviously it was meant for people who search for any old excuse to hop on the offended people bandwagon.

I would personally like it if you could go read that disclaimer again, and dial down the aggression a tad bit. Your generalized attacks on the entire country of Japan for a fictional work is bordering on prejudice and hate-speech and it's far enough I think. You made your point, and now you're taking it too far. Surely someone with the vocabulary you're slinging around can have a debate without tossing national hate-mongering at us like poo.
