Rights groups and government critics in Poland protested Tuesday after police temporarily detained a human rights activist for putting up posters depicting the country’s most revered Catholic icon with the LGBT rainbow on the halos of Mary and baby Jesus. Prosecutors in the central city of Plock said the woman has been questioned and has heard charges of insulting religious feelings and desecration of the icon of Mother of God of Czestochowa, popularly known as the Black Madonna of Czestochowa, a painting housed at the Jasna Gora monastery in the city in southern Poland since the 14th-century. The activist, 51-year-old Elzbieta Podlesna, last month placed posters with altered images of the icon on walls, garbage bins and mobile toilets near St. Dominik’s church in Plock. She did not physically damage the icon, which was venerated by pontiffs including Pope John Paul II.
