The Sri Lankan civil war isn’t a religious conflict.
Many of the LTTE’s top cadres were Hindus and Christians.
MTCC, you are right and wrong. It’s origin is ethnic and the war was primarily Sinhalese v/s/ tamils. However, the Tamils were mostly Hindu with Christian and Muslim minorities and the Sinhalese were mostly Buddhists with some Christians. It is portrayed that the Buddhist clergy are against compromise, but that is mostly due to their ethnic background rather than religious.
