Homer's Phobia

Homer's Phobia is the one of the LGBT-themed episodes of The Simpsons. In the episode, Homer dissociates himself from new family friend John after discovering that John is gay. Homer fears that John will have a negative influence on his son Bart and decides to ensure Bart's heterosexuality by taking him hunting.

Plot
Needing money to pay for a repair after Bart damages the gas line, the Simpson family visits "Cockamamie's", an offbeat collectibles shop, hoping that it will purchase one of the family's heirlooms (an "authentic" civil war doll which turns out to be a decorative liquor bottle). Homer meets John, the antiques dealer, who explains that much of the merchandise is there because of its camp value. Bart and Lisa take an instant liking to John, and Homer invites him to the Simpsons' house to see the campy items that the family owns. The next morning, Homer tells Marge that he likes John and suggests they invite him and "his wife" over for a drink some time. Marge tries to hint repeatedly to an oblivious Homer that John is gay, and when she eventually can't she tells him face to face and Homer is horrified. Homer's attitude towards John changes completely, and he turns against him, refusing to join his tour of Springfield. The rest of the family joins John and has a good time, but Homer is upset with the family upon their return. The rest of the Simpson family continue to enjoy John's company, especially Bart, who starts wearing Hawaiian shirts and dancing in a woman's wig. This makes Homer uneasy, and he begins to fear Bart is gay.

Homer endeavors to make Bart more masculine by forcing him to look at a cigarette billboard featuring scantily clad women in hopes Bart will be attracted to girls, but instead Bart gets the urge to smoke "anything slim." Homer then escorts him to see a steel mill to show Bart a manly environment; however, much to his surprise and dismay, the entire workforce is gay, and during their breaks they turn the mill into "The Anvil", a gay disco. A desperate Homer insists on taking Bart deer hunting with Moe and Barney. When they cannot find any deer, they decide instead to go to "Santa's Village" and shoot the reindeer in the corral, despite a tearful Bart being reluctant to do so. This backfires when the reindeer attack them. John, with the help of Lisa and Marge, uses a Japanese Santa Claus robot to scare off the reindeer and save the hunting party. Homer accepts John, more or less, and tells Bart, who is still unaware of his father's concerns, that any way he lives his life is fine with him. After Lisa informs Bart that Homer thinks he is gay, Bart is stunned. The episode ends with everyone driving off in John's car.

Just before the end credits a dedication to the steelworkers of America is shown, reading "Keep reaching for that rainbow!"
