My fave scene ever in a movie.
I used to think it was about skin-color and hair texture -- as that was always the way / the narrative that was pushed.
But, I have to say I guess it really was classism, not wanting to being attached or connected to the "blacks" from the South -- the newly emancipated blacks -- guessing they wanted to be seen as better and different to Whites -- to keep their status or something.
Like
@IllmaticDelta said -- very similar to the FPOC and Enslaved dynamic.
IMO Being light-skinned, having certain features or different hair textures -- didn't really come into play if looked like that --- when moving to the North. Especially when you still couldn't read, write and came from the South - aka newly Freedman/women or their children.
I don't know... I am still trying to understand.
