As a child following the Civil.Rights movement and struck by the injustice it fought, I discovered James Baldwin.

(Which prompted a librarian to try to direct the little 10 year old white girl back to the children's section.

"I've read Mr. Baldwin's other books, I may as well read this one, too." I replied.)

But as it turned out, our town library had censored Baldwin, much as this documentary has 46 years later:

I didn't discover Baldwin's earlier novel of a doomed homosexual love affair, Giovanni's Room, until late in the 1970s, during the Gay Rights Movement

They do mention that he's homosexual in the FBI file which is typed across the screen about midway thru the film.

There's also the part where Samuel Jackson is narrating Baldwin's words about his time in Puerto Rico, where he mentions that he was driving with his lover Lucien Happersberger listening to the radio when the news of Medgar Evers' death was announced.
