I don't agree with Dire Bare and think that Pemerton has the much more accurate view of the material.Thank you. I was just trying to gauge how much of it was was situating it as being reflective of "an exotic part the real world" (as opposed to making it "just more pastiche like we did in the PhB". I haven't actually read a copy for decades, but would believe some of the inside is troubling.
The most offensive material, IMO, is on the front and back cover; the title and the "exoticism" come hither.
The next major issue is that melange of various distinct histories and cultures as the "Orient" when it is primarily Japan and China, and specific tropes and periods of time for each.
Other than a few other missteps, I would argue that it less offensive than most material produced during the "golden age" of '74-'85 of D&D, and unlike say, Deities & Demigods it was at least trying to be respectful, especially in the context of its time.
