“What Would You Do?” tested people’s acceptance of transgender with a scenario set at Colonial Diner in Lyndhurst, N.J. Carmen Carrera, a 26-year-old transgender woman who has appeared on “RuPaul’s Drag Race,” played herself as if she were a waitress at the diner. Kevin, an actor, played a longtime customer back from a yearlong trip who deplores that the waiter he knew and liked as “Christopher” is a woman. “What the hell is the matter with you? Look at yourself! You’re a freak!” Kevin said.
