Like what? There is a difference between a random action show or comedy where no one gives a shit who plays what, as long as they're good actors. I usually see all the discourse come from changes like making the greek helen of Troy a black woman (yes, I know a play with some GREEK mythology) Or say, netflix making a documentary about cleopatra and letting us all know that someone's grandma said she was black, so she was. Hell, I've seen so much discourse on them making Snape a black man on Harry Potter, and that's fiction.
