The Goa Inquisition was probably the worst and involved torture and murder of thousands of Hindus and the destruction of many Hindu temples over a period of several decades. It was done by the same groups that promoted the genocide of Native Americans. But Church policy all along has been that Hinduism is bad and unless Hindus convert they cannot be saved. This easily gives rise to excesses. After all if I believe that if you don't join my religion you will suffer in eternal hell, for your benefit I must do everything possible, which easily leads to excesses.

5. What are the reasons for the sudden anger against the Christians?

The anger is not so much sudden as that today we have a more aware Hindu populace and a larger media forum for airing such grievances. Oppressed religious and social groups of all types are now making such protests. Christians will more quickly protest against Hindus if they feel that Hindus are not treating them fairly.Hindus have actually protested a lot less than other groups, though they have more commonly been the targets of denigration. Such a Hindu awakening was inevitable. The real question is why it took so long. Another issue is that the Hindu reconversion movement has started, which Christians find threatening and highlights this issue.
