I agree! It absolutely is disgusting when people become outraged by the existence of a woman or someone who isn’t white in a movie.
And vice versa.
I welcome many different ideas being explored in fiction, unlike Stephen King!
King, King, King. Read him much?
I’d suggest the matter is a bit more complicated. King was raised in Maine, and most of his stories are set in Maine. Maine is as lily white a state as you can find, and as a result, King probably has less real-life knowledge of people of color than almost anyone you can find in the public sphere.
Now, that’s not a criticism of King — — but the artist is a product of his environment, and most artists tell stories using characters they know, not characters they don’t know.
As an example, as a Muslim, I suspect that if writers who have never met a Muslim try to write fiction with Muslim characters, we’d end up with a bunch of stereotypes which I would either find absurd or insulting, one of the two. Maybe both.
King knows white people. He’s really good at writing stories where white people butcher and murder other white people. Let’s leave him alone and move on. :-)
