I think we can be honest:
Anyone pissed to the point of getting literally angry online that she isn't white is racist. Full stop. Period. End of story. Even if they don't believe they are.
It's 2018, the world is rapidly becoming less white every day. Stop expecting casts to be all white. Fantasy, sci-fi, or otherwise. Existing IP doesn't get a free pass from this.
Sorry in advance if some wording is bad, i don't want to hurt anyone but im not english native, so i do my best.
Is it really racism ?
I'm not angry, it's their tv-show after all, but Ciri has never been refered as black in the books, so why use a black woman to play the role ?
Blackwashing a character is not better than whitewashing.
If a character is black, use a black actor, if a character is white, use a white actor, if a character is asian, use an asian actor, if a character is a man, use a man actor, if th characer is a woman,use a woman actress.....
I don't see racism here, just a will to see a character be like the one in the original.
But i agree that th backlash is way to much and shouldn't be that hatefull.
