Neither Sinhalese nor Tamils are Muslims. The fight in Ceylon is over Land, not religion. The Sinhalese want to maintain supremacy, while the Tamils there are not willing to be subordinated. During the early years of India's Independence there were countless agreements, between Nehru and Bandarnaike and so on, but the Sinhalese did not actually implement them, so the Civil War broke out. Naturally there are those who want to roast their Meat in the Fire, but the fight is basically over the Land.
