And then I somehow fell upon this nice, succinct description of the problem with that book/movie:
the structure of narratives like The Help underscores the failure of pop culture to acknowledge a central truth: Within the civil rights movement, white people were the help.
The architects, visionaries, prime movers, and most of the on-the-ground laborers of the civil rights movement were African-American. Many white Americans stood beside them, and some even died beside them, but it was not their fight — and more important, it was not their idea. (Entertainment Weekly)
