i agree one hundred percent with everything that is written above and want to add that i often see people talk about using pbs of color in a way that feels like they're just checking off a box and that they need to diversify their cast so they need to find someone who is not white to use. it makes me uncomfortable because while i agree that diverse casts are wonderful and essential the attitude i see around makes it feel like a checking off of boxes.
i feel this especially to be true in hp race swapping where people will pat themselves on the back for playing traditionally white canon characters as poc without thinking of the implications behind it.
