A court in the central Russian city of Nizhny Novgorod has jailed a woman for wearing rainbow earrings, the human rights group Egida reported late Wednesday, marking the second case of its kind after Russia banned the so-called “LGBT movement” as an “extremist” organization in November.   According to Egida, law enforcement agents tasked with combating “extremism” detained the woman after a group of “aggressive people” approached her and her friend at a local cafe and filmed them on camera.
