Maybe some black people like to see shows with diversity, too.
In some other post someone was commenting how their wife, who is a director of advertising, got complaints for using a white female hand for an advertisement. I proposed using profile information to show people advertisements of people that matched themselves, but that was met with disdain in HN. It was argued that we need more diversity, not pigeonholes for people to be isolated in their subcultures.
Honestly when I read the title, I immediately thought, "Drinking fountains for black people."
