why not just focus on a good story? Why does race have to factor in to it?. If i tell a gut wrenching story about a father going through the loss of his child, should it matter if he's white?. No it shouldn't the only thing that should matter is the character, and seeing how he grows and develops. Shoving in diversity just for the sake of diversity isn't clever,or creative it's just simply lazy.
Speaking anecdotally, my first novel manuscript was complete shit. It was about a white ubermale protagonist who all of the beautiful white women in the book adored who was super heroic, badass, and was pretty much the textbook definition of a Gary Stu. My writing associates, rightfully, savaged me for it. It read like a bunch of cliche stock characters and was worth less than the cost of the printer paper it would take to print up.
Taking a moment to toss the manuscript in the fire, I took the elements of the story I liked and then started trying to figure out how to make it so it wasn't a steaming pile. Among other things, I did my very best to not make any of the characters stock characters. Thinking about their race, background, sexual attraction, and giving them backstories that set them apart made the world come alive in a way which hadn't before. I gave my characters realistic flaws, prejudices, and made them a variety of appearances as well as relationships.
The world suddenly felt far more "lived in" as we had Jewish, Hispanic, gay, straight, and lesbian characters who all existed in a world which was full of flaws as well as tensions. The backstories flowed into the narrative and there were interactions which didn't relate to the narrative. I published the book as
The Rules of Supervillainy and of the 100 or so reviews I've gotten on it, a good third mention the books diversity as a selling point.
I also got a good amount of hate mail but it was on Audible's bestseller list for a week and on the humor best seller for four weeks.
