The 2019 Christopher Durang Season concludes with the hilarious Why Torture Is Wrong and the People Who Love Them, a play which turns political humor upside down in a raucous and provocative satire about America’s growing homeland “insecurity.” It is the story of a young woman suddenly in crisis: Is her new husband, whom she married when drunk, a terrorist? Or just crazy? Or both? Is her father’s hobby of butterfly collecting really a cover for his involvement in a shadow government? Honing in on our private terrors both at home and abroad, Durang oddly relieves our fears in this black comedy for an era of yellow, orange and red alerts.
