Years ago, I read a story with a first person narrator that dealt with a future in which racial conflict had exploded into an all out war. At the end of the story the identity of the narrator is revealed: throughout the story he seems to be a white man, but in the end he is black.
I don't remember much more of it, save for the fact that the character is walking through some form of underground, and that the story is set in the United States. The conflict seemed to be a gang war kind of thing, with regular weaponry. I read the story in the late 1990s, early 2000s, but it was not new, it was in an anthology I found in my school library.
It's not Aldiss's "There is a Tide". It had more of a 1980s feel to it.
