Attacks against Christians in India

In recent months radical mobs have attacked Christians and their churches in a number of Indian states. Ayesha Saldanha wrote a deep analysis on the issue in Global Voices:
Right-wing Hindu groups, such as the VHP, its youth wing, the Bajrang Dal, and the Rashtriya Swayamsevak Sangh (RSS) accuse Christian groups of converting Hindus, particularly from lower castes and tribal groups. It is alleged that Hindu activists in Orissa have tried to intimidate Christians to reconvert to Hinduism.
The renowned journalist Khushwant Singh explains this conversion business:
To this day, Christian missionaries run the best schools, colleges and hospitals in our country. They are inexpensive and free of corruption. They get converts because of the sense of gratitude they generate. Can this be called forcible conversion? Why donʼt the great champions of Hinduism look within their hearts and find out why so many are disenchanted by their pretensions of piety? Let them first set their own houses in order, purge the caste system out of Hindu society and welcome with open arms all those who wish to join them. No one will then convert from Hinduism to another religion.
