Thanks so much for taking the time to write such a substantive reply! I’m really enjoying hearing everyone’s perspectives, and I’m learning so much. I haven’t seen Birth of a Nation in ages (it’s not the kind of movie you watch to wind down), so I missed that reference. Thanks for pointing it out!
You’re the second person I’ve heard mention that the dancing kids might be meant to be African, and I think that’s right. Some of the dances they’re doing are out of African pop culture, not American.
