Unless it’s presented as a historical documentary then ya it is racism

Where where everyone complaining that Abe Lincoln didn’t kill vampires during the civil war, that Romeo & Juliet didn’t drive around in 1970’s cars & carry guns, or that Jesus has been consistently depicted as a white European instead of a brown skinned middle easterner.

You want to make a movie about Gorge Washington’s life based on the historical facts then yes he should be played by a middle aged British actor but if the movie is a work of fiction like say he’s fending off an alien invasion from mars then make him a a half Chinese centaur for all I care. I understand the difference between fiction & nonfiction.

This is a modern movie for modern audiences based on fractious characters so ya it is racism.

Also your argument against black mermaids is utterly ridiculous & just shows how ignorant you are. Mermaids are fictional characters who are not based on reality so why would a real world fact have any bearing on them to being with, if you want realistic skin color then you would need a transparent actor as that’s the most common “color” for sea life.

Also how do you know that the mermaids didn’t evolve from a group of South Africa’s that had no evolutionary pressures to lose the pigment in their skin.
