Mr. Kwan already pointed to the Kara-Tur campaign setting as another product that should no longer be sold, so he definitely doesn't want it limited to OA. I would assume the entire line of OA supplements and adventures would also need to be removed to meet his requirements, since they all rely on OA and Kara-Tur.And while I am not a huge fan of slippery slope arguments, anyone who is vaguely familiar with the older materials knows that this won't end with OA.
While he didn't find Rokugan as offensive, it looks like he was also critical of 3E OA (and it still has "Oriental" in the title), so I wouldn't be surprised to see that go as well. Not sure if the removal request would extend to the third-party 3E Rokugan books, but they do have "Oriental Adventures" on the cover, so it's possible.
And I also wouldn't be surprised if, after his analysis of Al-Qadim is complete, that product line is also deemed too problematic to keep.
