You just said that my comparison was shallow and thats it. Didn't have any sort of argument at all.
Then you just say that the skintone doesn't matter since it doesn't impact the story since he is a background character. And I think that is a valid take, so why if it doesn't matter since he is a background character did they make him black? It doesn't matter anyways since he is a bg character right? So why go out of you way to change it?
Then you say I shouldn't be bothered by it or even care, but that is simply stupid since if we reversed the roles, you and many others would lose their sh***. But I have realised that you seem to dodge that fact anyways.
Yasuke reference would be stupid aswell, he is a thing on its own, why add him to the shinsengumi. That looks stupid. Along with the fact that it shouldn't matter right? Cause he is a bg character right?
The only good and valid take is the last part, and that is that the author made it this way. But well that is at that point just stupid from the author then, he can make it like that if he wants, but at the end of the day there was no purpose in it and he just black washed a character. If an author did this the other way around by white washing, would you not say that is also stupid? Although knowing how much a story can be influenced by the pressure of your audience, it is not impossible that he was forced to make that character black for no reason.
