How on Earth do they explain a Negro Valkyrie?
The same way they explain a black Heimdall; these characters aren't actually Norse gods as such, but rather long-lived aliens who interacted with the Norse people of ancient times.
The same way they explain a black gatekeeper (or whatever that dude was in the “Thor” films).
Their audience primarily is a pimply faced high school male who is barely aware of anything outside of comic books, video games, & his cell phone. All wishing they had muscles like Thor but are too lazy to work at getting them. The previous movies presented Heimdall as black. (Irdis Alba played him!) This was I think deliberate because according to Norse mythology Heimdall is described as “the whitest of the gods”.
So they now have a black Valkyrie?

Cultural appropriation?
Vikings did raid North Africa.
They’re from another dimension, and completely different species. The Norse god aren’t actually Nordic, that just happens to be the part of the world they visited a lot back in the day.
So a woman Thor, a black Thor in a comic book movie is perfectly fine. Putting a woman Thor or black Thor in a movie about the Nordic gods if it is pure fiction is kinda ok. In a documentary, its not ok
