The movie "Brokeback Mountain" is specifically referred to in Kenji Yoshino's book, Covering: The Hidden Assault on Our Civil Rights:
"'Brokeback Mountain,' which spans two decades beginning in 1963, depicts cowboys trapped in the first two generations of gay history. The emotionally frozen Ennis can never fully embrace his love for Jack because he has been subjected to a particularly terrifying form of conversion therapy. When he was nine, his father took him to see a man who had been beaten to death for having 'ranched up' with another man. The heterosexual imperative reflected in that murder drives both Ennis and Jack to marry women. But Jack believes a different life is possible — he tries to persuade Ennis that they can inhabit a closet built for two. The tragedy of the film is that Jack is too far ahead of his time — it is the less courageous Ennis who survives."
