Sikh separatism from Hindus began and was encouraged by the British. By the time they left India in 1947, both communities were identifiably different. But when the country was divided, the Sikhs migrated en masse out of Muslim Pakistan to India. The loss of communal privileges they enjoyed during British rule made them an aggrieved community. The danger of their re-absorption into Hinduism gave birth to a fresh assertiveness that they were a separate community: Ham Hindu Nahin Hai. It found expression in the eruption of anti-Hindu bigots like J.S. Bhindranwale, anti-Hindu terrorism and the demand for the sovereign state of Khalistan. There was nothing ethnic about these developments; they were exploited by politicians, the state and central governments and Pakistan.
