And you clearly have a racism fetish, so I guess we all are flawed in our own ways.
Fiction will always be there to entertain, some works more close to reality and some more "creative".
As long as the author/artist doesn't claim that this is a historic (or similar) work, then you sadly will have to take your personal bias in pain and enjoy other work.
I have no interest in this story, but I wish all the readers that do enjoy this, lots of happy hormones!
P.S. I do wonder what your take is on the products of modern BBC(and co.) that do claim historical accuracy, while actually just fetishizing their own agenda.
