Having literally just black and beige white people isn't really diversity, and having white characters in stories and universes concieved of by white people seems to me like missing the point.
When I was growing up, there were lots of original stories with black people in them. There were cartoons, movies, variety shows, dramas, comedies, all about black neighborhoods and black families. There were superstar black actors who played black characters with regularity.
Compare today where instead of taking chances on letting people tell their own stories, the only way you can "include" minorities is to dip a white character in different strengths of tea and coffee.
I don't like it. I'm curious about the world, I want to hear music from all eras from around the world. I want to hear stories from all eras and all around the world. I want to understand how all different kinds of people think and see their values and understand how they push up against those values in the real world. Instead, we get a monoculture. Southern California and everything else is verboten.
