I'll trust Asian voices on how "okay" Oriental Adventures was, rather than folks in this thread who refuse to accept any progress towards a more inclusive D&D.
I highly recommend the Asians Represent podcast, where a panel of Asian-diaspora gamers go through Oriental Adventures (and later, other books) and discuss what works . . . and what very much does not.
I watched their first two-hour youtube video where they start in on 1e OA and I found it to be terrible analysis and it led me not to trust their analysis in general.
They spent an hour criticizing OA as intentionally sexually exoticizing and othering Asians by introducing the comeliness stat for Asians and not for normal D&D characters.
The comeliness stat had terrible and sexist agency removing mechanics that were awful all around and is worthy of criticism. But it was factually not introduced in OA to set up specifically sexy dragon lady and ugly Asian men stereotypes or to other Asians as different from normal Europeans with weird beauty and ugly powers.
It was not introduced in OA, it was carried over from normal core 1e D&D. It had been introduced in Dragon Magazine, then included in the World of Greyhawk Campaign Setting boxed set, and then into general core 1e D&D with Unearthed Adventures, and then applied straight with no modification in OA along with the other six ability scores.
The Asians Represent guys started in 3e and not 1e and were not familiar with 1e so they came across the new to them mechanic, which is fine. However, they then jumped right from not knowing into assuming it was created to other Asians and asserting incorrectly it was done to do so. If you did not know the background of 1e and the comeliness stat this factually inaccurate portrayal could easily lead to thinking how OA is treating Asians as exotically different and requiring different treatment based on sexualized stereotypes.
There are stereotypes of Asian sexualized exoticization and othering and they are real issues, but they are not things that 1e OA inclusion of comeliness does to separate Asians in the game as different from Europeans in the game. OA treats Asian beauty the same as European beauty.
This not knowing and jumping to their assumptions and asserting their assumptions as facts and not conjectures or impressions removed any trust I had in anything they said about things I did not already independently know. Both facts and characterizations.
Later the lead guy when told about the factual inaccuracy that was the basis of his analysis doubled down and said it did not matter because it was how it struck him at the time.
