I've read a few comments about the issue of skin color change, and I can't say that it makes me happy about it. I agree that changing the color of her skin made a huge plot hole, like, denying all the character development Claudia and her friends had in regards to it, it was a really bad idea to change something so consistent, and really sensitive matter at this point. I also agree that giving Claudia a different hair color, even if it was the tip of her bangs or a single part of her hair, but oh well.
But I would like to think that so many people being in a discussion about it gives me a bit of hope that people's mindsets about racism can change. Just like people will judge others based on their choices, gender, religion, etc, I still want to believe that in the manga, and in real life too, people will also accept others for their different choices. At the end of the day, everyone has their opinions, and make mistakes too. As long as there is respect, people will be able to be happy without questioning why they are being ostracized by the color of their skin or other stuff that brings discussions like this to the eyes of society every day.
