Nobody's upset about having a black girl in a shitty Disney movie. I fully support that there should be representation in media so children of different ethnic backgrounds have something to relate to when they watch this garbage. The problem is that when you take an existing white character and make it black, brown, yellow, whatever, you're sending a message that there is something inherently wrong with white culture. If this was an isolated incident, I'd probably be willing to give Disney the benefit of the doubt, sure maybe she was just the best person for the role. But it's happened repeatedly with Disney and the political agendas of the organization are so well known that it's hard to believe they're oblivious to their messaging here, and that it's anything but intentional. It's just as important for white kids to be comfortable with and proud of their heritage as anybody else.
So if you ever procreate (doubtful) and your kid grows up to be a self-loathing whitey and ends up joining Antifa or some shit, you can think back to stuffing your fat gullet full of popcorn while watching shit Marvel comic movie #43 and tell yourself that it was all worth it.
