A new form of protest against the government is spreading in Iran, as people participate in a viral dance and happiness campaign. Dancing in public is banned in Iran, but this recent act of civil disobedience has gained traction. It all started with an old man who energetically danced and sang in a fish market, which led to his arrest and sparked outrage. The government eventually retreated and the man, Sadegh Bana Motejaded, is now hailed as a national hero.
