1. So is there no religious reason behind the exodus of Kashmiri Pandits from the Kashmir valley? Is that what you are trying to say? Then in your opinion what is the actual reason behind the exodus of Kashmiri Pandits from Kashmir? Were they not Kashmiri enough? Please elaborate.
2. The whole issue of Kashmir is based on religion, it started with whether Muslim majority Kashmir should go with Muslim majority Pakistan or remain with Hindu majority India because the Hindu king of Kashmir decided to join India. Pakistan's political and jihadi intervention in Kashmir is also because Kashmir is a Muslim majority state that Muslim majority Pakistan consider to be their legitimate part. And the root cause of dissent among the Kashmiri Muslims of the valley is also because they want nothing to do with Hindu majority India, and they don't want Hindus, Shikhs, Buddhists, even Shia Muslims in their Sunni majority Kashmir valley. It's all about religion. Kashmiri nationalism is just a cover that some use.
Secularism is good, it is important, but let's not allow it to prevent us from calling a spade a spade.
