I think the Witcher example is an imperfect comparison here. Racism in the Witcher is often a plot point and is usually very clearly presented as bad and the racist behavior is meant to be wrong and we're meant to be uncomfortable with it. It's presented as something definitively negative and those racial tensions are a central part of the world's flavor.
I can't really think of many cases where fictional representations of racism, sexism or what else were presented as an endorsement of aforementioned.
Not the biggest fan of the recent push for their forced removal either, since this tends to leave these fictional settings feeling completely toothless.
I would bloody expect a world where entirely different SPECIES like elves, dwarves, orcs, dragonborn and the rest exist to come with a lot of racial tension, mutual preconceptions, disrespectful jokes and what else.
And I'm more than a bit puzzled at the idea of "calling out a companion for being racist", since I'm not sure it makes much sense that in such a setting the "insult" would have much of a grip, if any.
I can't imagine, for instance, calling out Lae'Zel for being a Githyanki supremacist turning into much more than a "Yeah, so fucking what?".
But that won't stop people having stronger opinions about the topic, I'm sure, and I can't really say I care to a degree of being willing to argue about it.
