India, what you know of today, isn't India what existed before Islam or christianity started spreading into Asia. The historical India, is now split over Afghanistan, Pakistan, Certain parts of Iran, Bangladesh, Nepal, Sri Lanka, Certain parts of Tibet and Bhutan. Bulk of those countries now is populated mostly by Muslims, Christians and Buddhist. The Muslim and Christian population in India itself is >15%. So >50% of the original population, moved to new religions. And you keep hearing of people moving to other religions from Hinduism all the time. This is a major source of political strife in India today. The caste system did/is doing enormous irreparable damage to the Indian society and has done over the ages. The moment any new religion was available people have moved on to it in mass numbers. The oppressed people always move on to what works for them. Don't blame them, nobody changes their identity that easily. Its only when things go beyond bearable do people make these decisions. And beyond all any conversion to a new religion is a late process, the early process involves divorce from the existing religion. You can't stop change of heart.
