Root is about a black slave. the entire story is about the color of his skin and origin from africa as this is the very reason he is a slave in the first place. The character arc is dependant on the color of his skin.
Well, it could be a modern social commentary highlighting how modern-day racism targets whites.
But if the slaves were all black (they weren't) then the non-slaves must have been non-black, right? So programmes where all the aristocrats are cast as black characters are equally wrong and unrealistic, right?
So, I'm asking: What character trait or story is dependant on Bond being white? this is an honest question. I guess there could be something, I'm just wondering what?
To be believable, he has to be white. He wouldn't be in the social circles / position he was at the time if black.
Why couldn't Harry Potter be a Chinese girl? Because he wasn't written that way, and why should he be?
