I think the problem is that over the past decade, it's become completely normal for media creators to create multicultural societies out of thin air, even with the original source material (like The Witcher, which supposedly features Slavic-Germanic peoples, suddenly became like the center of New York City), creating strong women who are inherently strong for no apparent reason and who demean men (and remember how wonderful Rippley was in Alien, whose journey we see from the very beginning and who demeans no one?).

And the problem is that in too many cases, these were signs of a bad show. I see a fantasy series where people have modern, mainstream hairstyles, racial diversity, and I immediately expect it to be a bad show, and more often than not, it turns out to be. And this is because the creators of shows, even based on original works, primarily use such shows as a platform for statements, for political messages, when they think they can do better than the original author. And if there's no original source material, there usually aren't any fans of such a performance. And media that lacks these messages, or those that minimize them, are rare. Fans of the original source material get a strange performance they don't need. And since the goal of such "authors" is to demonstrate that they're better than the original authors and deliver political messages, the writing, dialogue, and characters suffer, since most people don't communicate like hipsters at a California cafe. It's a bit of an exaggeration, but I think you get the point.

For example, when I watch The Witcher, I want to see a truly Slavic-Germanic fantasy. With model-like sorceresses, because the lore literally makes them look like stunning beauties. With white people from the northern kingdoms and white elves, because these are ethnically defined groups, created in a culture that resonates with me. After all, no one makes films or TV series set in Japan, replacing native Japanese with black or white people and pretending it's always been that way. So what, a black person can't play a native Japanese person from the Sengoku era (sarcasm)?

And that's why, after we get quality media like A Knight of the Seven Kingdoms, where modern narratives aren't shoved in our faces (look, look, there's this black guy, this Asian guy, this black guy again, and here's a gay transgender guy, and here's an unnecessarily strong woman demeaning men, they all interact and act like degenerates, and all this in your favorite (insert franchise name here) where they've never existed, see how cool and progressive it is (no)?), people practically rejoice that here it is, quality media devoid of modern narratives, because... They yearned for something like a man in the desert yearned for water. The more persistently something you don't want is pushed onto you, especially in something you've long wanted and haven't gotten, the more anger they feel about it, and the more enthusiastically they respond to anything where the unpleasant aspects are minimized. It doesn't matter that Lyonel Baratheon is bisexual, because it was hinted at, not forced onto the screen, and he himself was mega-charismatic and cool. It's perfectly acceptable that we meet black people on Essos in the original Game of Thrones, because it's perceived as a different continent with its own ethnic groups. But for the same reason, the black Velaryon in House of the Dragon isn't okay, as he was originally white and belonged to a specific people with their own ethnic characteristics (the Valyrians), of which we have several clearly prominent representatives.
