I mean, not for nothing, but do you think there's a reason we don't tend to get films made depicting happy people singing with animated birds, but set in Third Reich Germany?
I guess The Sound of Music shows a mostly happy world, but much of its dramatic tension, particularly in its second act, is at least built around acknowledging and confronting the very real dangers and terrors of that era. Given that the NAACP even criticized SotS upon its initial release, these are not new criticisms.
EDIT: I also keep seeing people saying that Disney "gave into the mob" or "the outrage" or whatever, but can we actually see evidence of widespread, mainstream calls for the removal of the Brer Rabbit story from Splash that got any traction? As of now I don't see a reason to doubt that Disney had this planned back in 2019, given the detail in the concept art, so I'm not sure where people are getting that from.
