Thank you, Roundy.
Yes, diveristy is good. I forget where I read it but it was an article about representstion. Minority groups are often bombarded with media where the just don't identity with it. Where the lead role or most of the actors don't look like them. Or clicking on the news and seeing little to no representstion there or in politics. And its rough. Children can sometimes look and say "they don't look like me" when looking at characters in their shows/movies.
To them, having a black mermaid, even if the movie bombs, is uplifting. And once you do it once, its not a big deal to do it again.
Like Obama being the first black president. Its now a "well, now ee know we can do it" or a "we did it already so it doesn't seem weird anymore".
So in these cases its about
1) giving minorities representstion so they can feel like they belong.
2) giving inclusions so such things become normalized.
