In case you don't remember, the original animated Disney film was a train wreck of leftist shit that completely stripped the source material of everything that was culturally significant in it.
No longer did the lead become a saint who watched over and interceded for her siblings from heaven, but instead she ascended beyond her nature, like a transhumanist wet dream, leaving behind her penis-towered palace beneath the sea to be married to a vapid billionaire by a priest sporting a boner.
Sure, you may have really fond memories of its catchy tunes and cute sidekicks. That's expected of unthinking children.
So, yes, they race swapped a main character. But before they did that they raped a Christian fairytale of everything that made it good and turned it into trash. It was an entertaining cartoon for kids. It was not a significant part of western white heritage.
I'm much less a fan of the sort of Christian fairy tale that focuses on the premise that the character in question is the soulless other. Give me The Lord of the Rings, not "Ariel tortures herself in pursuit of that which all humans receive as their birthright."
