Here's what else I just wrote to the cuddlies at LC:
re: http://id.loc.gov/authorities/subjects/sh97006812 "Racism in popular culture," it would be a real help if there was an additional heading, Race in popular culture.
I'm cataloging an item named Nerds of Color: Sci-Fi/Fantasy/Science that addresses people of color in comic books and television. The contributors discuss the Latino and Black creators, characters and motivations, outside of the Caucasian gaze. I'm not sure what other heading to assign. While I don't love the term, Minorities in popular culture might also do, as well as ...in science fiction headings.
Thanks for your help.
Jenna
