Another issue is this cynical, corporate idea that if you simply change an established character from white to black - or male to female - you're advancing the arc of diversity/social progress. In reality it's often just a cynical marketing attempt to attract black/women/etc audiences. Which is fine if we could simply accept it as such. They aren't interested in exploring black stories - unless it's some weird trauma based shit - they just want your money. So Little Mermaid is black. Her mother will be black, and her father is white (well, Javier Bardem). Because of course Disney will never depict a black family, much less a straight black male character, in anything today...
I get that they're weirdo racists but jeez, why do people care about this stuff. It's obvious what the agenda is ($). If you don't want to see it, don't see it.
