Sorry man, but you seem to be trying to de-legitimize their viewpoints because . . . . they are human and make mistakes.
You're not wrong. The bit about Kim Mohan was a bit cringey. There are other, similar examples. There are times where some panelists go looking for problems and find them . . . . only to be reined back in by others more familiar with the tropes.
I've listened to about half of the podcasts covering Oriental Adventures 1E, and a bit of the episodes covering OA 3E, the Kara-Tur boxed set, and the Al-Qadim boxed set. This group makes mistakes and misunderstandings all the time . . . . . but if you listen to even one of their podcasts in its entirety and your takeaway is . . . . about their screw-up on Kim Mohan's ethnicity . . . .
The Asians Represent panelists aren't elected representatives of the Asian-diaspora community. They're just a bunch of Asian nerds who want to talk about their experiences and views on how D&D and other RPG games deal poorly with Asian cultures. They are all hardcore nerds, but not all of them play D&D, and some of them who do have only started relatively recently. Several of the panelists are academics who specialize in Asian cultures. The panelists also change over time, with some regulars showing up almost every episode.
None of the panelists, to my knowledge, "grew up" with Oriental Adventures . . . . they're not that old. They are looking at OA with 21st century, millennial generation eyes. This is not a ye-old grognards OSR podcast. If you watch a couple of episodes, you start to get a feel for the regular panelists and their level of familiarity with D&D's development in the 70s, 80s, and 90s . . . . but none of them lived it. And that's okay.
They also, very purposefully, don't do any homework. Many of them have no experience with these books until the digital file is opened and reviewed, page-by-page, during the podcast. It's a choice that I'm not sure would be my preference, but it's a legit choice.
If you watch multiple episodes, you'll also see them gain more focus, start to coalesce their views, and even walk back some statements from prior episodes. These podcasts are messy, but the best out there on the topic and very good over all.
EDIT: I'm probably coming in too hot with you, @Sacrosanct, and also @Willie the Duck. If I've misunderstood your point, or piled too much into my response I apologize . . . . I'm just so tired of the crowd who refuse to see the issues with these books. I probably need to step back from the conversation for a while.
