Disney has become a more inclusive media company for this exact reason. The tireless effort of activists that "pro-black" armchair militants now call pro-lgbtq fronting scammers is why there is more diversity in the media today and I ain't mad. We ain't begging. Diversity is what these young folks want and it's what Disney wants. And we made that happen. There ain't a single white kid on Tik Tok or social media today who would prefer to see only white people in their media. Those days are far gone, commercially, culturally, and morally thanks to a lot of activism.
Like you said, we can fight for better representation in the media in general and build our own media at the same time, which is what's going on. There is really nothing to complain about here. Let the Chinese be mad that a movie studio that they once relied on to give them heart warming pictures of white people is now inclusive of black women too.
If they don't like it, let THEM make their own Disney-esque movies the way they want until they get tired, stop being archaic arrogant barbarians, and move on. Not our grudge, not our problem.
