I also think there are 2 things being described.
Again there's people saying this character has traditionally been _____ race or had _____ look and people want filmmakers to stick to that. We fanboys do that all of them time. And that's not necessarily wrong or racist just like it doesn't make you necessarily less racist to be fine with diversity in Hollywood. I mean how many people do we see say things like "Black Lives Matter" or "MeToo" or call for diversity and it's revealed that they're part of the problem.
Then there are things like there should be no minorities or women in prominent roles. That weirdo point of view. I personally honestly see happen more to women than race stuff like Gears of War, Call of Duty, Star Wars sequel trilogy. But obviously they go for whoever isn't a straight white guy
