@Etaya The fuck? Is that all you got out of it? That everybody is racist? No, everybody starts treating her better because she got the blessing of the light spirit. Not simply because she turned white. Their fear wasn't towards her skin color at all. Nobody even mentions it!! Only the light spirit said something about it, and what she said was sorry, that she didn't expect her skin color to change. The fact that her skin turned white became a proof for people that she truly is now blessed by the light spirit.
The author herself is not really making having black skin to be a problem. The people who matter, the good people here do show regret at having her skin turn white. Don't forget, the opinion of those around her always belittled her, if they are racist it doesn't mean the author is too. She never tried to make the general people be good people here. She made them subjective to their own beliefs, and she makes it known that they are horrible people for doing that.
Even if the author did feel that way, you shouldn't ignore that she tried to imply many times that her skin color was never the problem. It was just an indication similar to her black hair and eyes.
