Racism is bad ? , if you are watching with your ass then yes you may reach this conclusion, but Oda never say that something is good or bad , he shows us the perspective of the different sides , he dives deep into the psyche of every side , and we have to decide who is right and who is wrong ,
damn , Oda showed us that even the celestial dragons are victims without saying a word , that’s what they call nuance and subtlety, they are something that you will never see in naruto because kishimoto is not a talented writer, he can barely do the basics ,
i will tell you a secret , friendship is one of the background themes , that’s why even the antagonists care for their friends , it a thing that you must over look it , it is the surface of one piece , if this is what you got from the series , then it proves what kind of reader you are
