I'm just making this poll out of morbid curiosity. There was quite a bit of outrage when Ciri was rumored to be played by a black actress in The Witcher Netflix series despite her being traditionally white. Likewise, casting Michael B. Jordan as Johnny Storm, who is, of course white in the shitty Fantastic Four reboot (Fant4shit) drew a lot of ire from fans, even though it was probably the least problematic thing in that godawful movie tbh (I'd say making Dr. Doom, one of the most badass characters in comics a trash-bag wearing, poor man's Imhotep was so much worse). Casting Zendeya as Mary Jane was also heavily criticized as was casting Idris Elba as Roland in The Dark Tower, even though it turned out she was actually playing a whole new original character in Spider-Man: Homecoming.
The same is also true of whitewashing minority characters. Casting Sco Jo as Motoko Kusanagi in Ghost in the Shell drew rabid backlash as well as we all very much know. However, the populace seems to be more accepting of whitewashing characters than the opposite for reasons as money and "don't cave to PC culture!"
As for me, I think, and always have thought that characters should always follow the source material. I'd be just as upset about Jason Statham being cast as Blade or Black Panther as I would SWM characters being needlessly gender/racewashed. I don't want Tommy the Green Ranger being turned into Tomi in the rumored Power Rangers sequel or Ellen Ripley being turned into Allen Ripley or any of that shit.
