"Some Indian Christians are being persecuted by some Hindus."

It is far more complicated. When tribal people and lower caste Hindus become Christian, traditionalist Hindu organizations target Christians. These Hindus fear that success among lower caste Hindus will dilute the national Hindu voice and vote. Even Gandhi was opposed to Christian missionaries, calling into question the appropriateness of conversion itself.  Many Hindus also see Christian educational efforts (especially Catholic) as a threat to the social order, destabilizing it, pitting lower castes (most of whom are Hindu) and tribal people against upper caste elites. (Remember, many Jesuit/Catholic schools -- very tolerant -- have predominately Hindu students.) Needless to say, educated Christians do better on human development indices in education, LITERACY, neo-natal and post natal care, etc. This can pose a threat to the Hindu social order. Ironically, tolerant Jesuits are inviting "worried" Sharan to Georgetown! lol
