The significant majority of people in a position of power in the books are women. The books have a massive array of races and cultures, from the multicultural and multiracial Seanchan to the Sea Folk who are depicted as dark black and the Sharrans who are mostly shown as SE Asian. The only predominantly white people are in the Midlands and the books continuously shows the many surrounding cultures to be more successful than the midlands (who are plagued by palace politics); one of the foundation events of the world's recent history is the Aiel War where the Aiel pretty much invade the midlands to kill one of their kings with no difficulty and just return home and don't even consider it an act of war. The other people on the same subcontinent are shown to be of varying cultures; the heroic northern states are largely described with asian features, the ones in the south are very tan and similar to latinos.
The books are primarily told through the POVs of the five Emond's field characters, two of which are women. Of the two, Egwene becomes the Amyrlin seat in a long plot through the books that focuses on overcoming trauma, sisterhood, female mentorship, placing your own goals over those of men. I won't talk about Nynaeve cause she my favourite character in fantasy fiction so I am biased
So yeah, the Wheel of Time did not need help to celebrate women, it does so constantly with Egwene, Nynaeve, Birgitte, Moirane, Verin, Siuan, Morgase and so many others. The main cast DID lack diversity because they all originate in an insular community. I understand why this might be changed (though I would hope that if we make Emond's Field race blind then we would do the same to e.g. the Sea Folk). Personally I'd have changed the Aiel and through them Rand.
Now don't get me wrong. Obviously many people do hate the show simply because it has female representation and "forced" diversity. But I cannot believe that would be the fandom at large. An incel would not go through multiple books that focus on Egwene.
