What is that? My sisters birthday in 86? What?
That slogan is a Sendero Luminaso a/k/a Shining Path slogan about the deaths of more than 250 people in a prison riot in Peru... that were agitated to riot by SL communists. As I recall, SL is Maoist.
From wikipedia:
When it [Communist Party of Peru a/k/a Sendero Luminoso] first launched during the internal conflict in Peru in 1980, its goal was to overthrow the state by guerrilla warfare and replace it with a New Democracy. The Communist Party of Peru believed that by establishing a dictatorship of the proletariat, inducing a cultural revolution, and eventually sparking a world revolution, they could arrive at full communism. Their representatives stated that the then-existing socialist countries were revisionist, and the Shining Path was the vanguard of the world communist movement. The Communist Party of Peru’s ideology and tactics have influenced other Maoist insurgent groups such as the Communist Party of Nepal (Maoist Centre) and other Revolutionary Internationalist Movement-affiliated organizations.[1] The Peruvian guerrillas were peculiar in that they had a high proportion of women. 50 per cent of the combatants and 40 per cent of the commanders were women.[2]
