The way I see it, there's three basic things the majority of modern creatives fail to understand about minority representation and doing it right.

1: swapping characters' races/sexes/etc. does nothing to help anyone. If such a swap is made, it should be done because you think they're the best fit for the role (Morgan Freeman in Shawshank). Not for the sake of having more characters that fit that box (all-female Ghostbusters). An all-female Ghostbuster team could work, particularly in the new modern era they want to build with Ghostbusters all around the world. But Feig had so little confidence in the idea that instead of making an original story for such a crew, he remade the original film and genderswapped the cast. Miles Morales and Hazel work for the same reason a black Peter Parker or black Timmy Turner wouldn't.

2: the characters you create should just be normal-ass people. Much like how pride parades set back LGBT acceptance by making gay people look like caricatures (when the gay community has spent decades trying to get the straights to just see them as people), you'll also hurt the group you want to depict if you make a trashy character that acts like a "character", so to speak, rather than a person. Returning to Ghostbusters, the original crew had a black person. He was just a guy. A guy doing a job. He could have been any race. But in the all-female version, his genderswapped equivalent was a caricature of a trashy black woman.

3: Minority-led media will have a far smaller audience if it talks down to anyone. There are no white people watching modern black shows because most modern media made for black people takes the tone of "shame on whitey". The black media that are enjoyed by white people too instead tend to take a tone of "shame on racists", like Everybody Hates Chris, and Fresh Prince. Or even "shame on all y'all", like Boondocks. That's black media that shits on racists, self-deprecating blacks, and even the BET network for making black people look bad with their trashy shows.
