Marcello Crivella, the evangelical mayor of Rio de Janeiro in Brazil, attempted to ban copies of the comic Avengers: The Children’s Crusade from a book fair, stating it held content that wasn’t suitable for children. 

The graphic novel featured an image of a kiss between two men, which Brazil’s biggest newspaper, Folha de S.Paulo put on the front page of their issue, according to The Guardian. The editor said the purpose was to “throw light on censorship threats.”

“It is an attack on freedom of expression,” said Mariana Zahar, the vice-president of the National Union of Book Publishers, which organised the book fair, according to DW. “We will fight this to the end.”

Brazilians have linked the attempted censorship by the mayor to the government under conservative and homophobic President Jair Bolsonaro.
