You've got a certain type of people out here who want to get mad over a black Ariel, but won't keep that same energy when it comes to Hollywood whitewashing Ancient Egypt, the Bible, and all of these anime/manga/cartoon adaptations they've been coming out with recently(Dragonball, Ghost in the Shell, Speed Racer, Death Note, Last Airbender).
Sounds about white.
I'm not normally in favor of changing up iconic/established characters like that since I prefer to see original black stories and black characters instead. In this case though, I'd say the WS tears are worth it.
