Disney's new black princess...what's the big deal?

Please do not bring up anything to do with anything that happened back in the day...ie; slavery...geez. I mean, so what if there is a black princess...aren't black people segregating themselves once again by announcing how big this is? Cant it just be a princess. Oh my other question, will black people every be satisfied? They cannot be happy that there is a black princess but now there's an issue of why the prince isn't black?
