This situation somehow remembers me of a post in my favorite band's Facebook when they went to the US for the first time after more than a decade without playing there. The post said something like "Yes, after all that time, we'll tour the Western Hemisphere again!" Well, the only problem was that not even six months had passed since they had toured Brazil and the rest of SA for the last time. Apparently we were not Occidental enough for their social media.
From what I know, the concept and basic ideas around "Orientalism" are not given for sure even in the field of anthropology. Edward Said is the kind of guy who has a lot of fans, but is very far from being an unanimity. Zeb Cook, on the other hand, was genuinely interested in Japanese culture, working with the kind of source that a guy like him could get in 1985, and trying to present that stuff to D&D gamers in the best light he could. It hurts me that people are seeking the removal of books that, if a bit outdated, do not carry a single moment of hate speech. This is just book burning, and I wouldn't be fool to believe that those who are seeking to start this process will be willing to stop before only the things that they find appropriate are allowed to go public and be sold. I hope WotC do not pay attention to this plea or any other of similar nature.
