“If we look at the history of resistance in Myanmar, we were quite aggressive and confrontational, with this history of bloodshed,” said Ko Kyaw Nanda, a graphic designer whose protest art contrasts green pig heads (the army) with ruby red heels (Ms. Aung San Suu Kyi). “With this new approach, it can be less risky for people, and more people can join.” Myanmar’s military, which has ruled the nation for most of the past six decades, has locked up more than 450 people since the coup, according to a group that tracks political prisoners. The new regime has drastically diminished civil liberties, and its long history of violently suppressing dissent lingers. Security forces have shot and beaten anti-coup protesters. On Wednesday evening in the city of Mandalay, soldiers swept through an area housing railway workers who were boycotting work, shooting multiple rounds. At least one person was confirmed injured, but the weapons of dictatorship have not deterred peaceful demonstrators, who have depended on humorous memes and protest art to carry them through.
