A lot of what was once hip and cool and popular, etc in the 70s or 80s or 90s, especially in English-speaking countries, whether in music or movies or books or RPGs, is not now. People need to take off their rose-colored nostalgia glasses and look at things again and stop supporting stuff that is an insult to their fellow human beings. The old Oriental Adventures/Kara-Tur stuff is part of this and I just don't see how it can be updated to be more accurate without the old, bad stuff coming up again. I would rather use the Asian-themed parts of Golarion from Pathfinder, than to use Kara-Tur again, and that area has it's own problems as well.
