“Not my Ariel”

Completely fine with it. As long as she does a good job in the role I'm happy.

Many posts criticising this also talk about what if Tiana (black princess from princess and the frog) becomes white.

Not the same though - Tianas race is relevant to her story, just like Mulans and Pocahontas's. Ariel's just a fish person.

Considers whether to do the washing up liquid joke again...

Is it right to reduce the representation of white people, in majority white countries, where white people are the main audience? If the reverse were happening, the loony left would never stop screeching; imagine a bunch of white people mass-migrating to India, and then demanding that Bollywood becomes at least 50% white?

I find it unnecessary, sort of like they did it just for the sake of diversity and playing along, you don't need to make Ariel black, I don't have a care in the world what colour a character is, what I do care about is doing it because you feel like you need to for the sake of diversity, you don't need to do anything, that's what's getting the racism pot cooking, this right here, if you are honest about not caring about a persons skin colour then you won't act based on skin colour, simple. Bond, out.

I do think the complaints are valid, reverse the roles, if ariel was black, and played by an asian or white actress there would be an uproar. I dont think white people care as much, they are just sick and tired of the double standard. Why is it okay for coloured people to represent white people but not the other way round? Yes diversity is great and all, but dont erase whiteness to fit it in, instead there should be original characters (like mulan and the princess and the frog chic).
Personally I do not give two flying fu*ks, but I do understand the complaints.
Coming from an asian if that carries anything.
