@tofugolem And another point.

In distopian fiction books, author may not describe race. So African Americans can see characters as black so it's a crescendo of existing practices.

But once you adapt it to movies you can't occlude race (and gender) anymore. So showing white characters suffering what African Americans know as systemic racism (but not racial, wink wink, we are oppressed *equally*) is a sort of cultural appropriation of being oppressed.
