How would a homophobe prove a man is gay?
Im writing a screenplay about a group of miners trapped in a collapsed coal mine, in one of the scenes the miners decide one of them will have to be sacrified due to the lack of oxigen, the guys with children back home are spared, so they have to decide between the single men, some of the guys suspect a young man is gay, he denies it, the group wants to prove the young man is gay so they can sacrifice him based on their homophobic logic. The question is; How do the miners go about to find out if the young man is gay???
