Reception
Many Hindus in India, especially those affiliated with Hindutva-oriented organisations such as the BJP and RSS, are supportive of Ghar Wapsi efforts to counter what they perceive as mass conversions to Islam and Christianity and to a lesser extent Buddhism, among Dalit Hindus in India. Some secular groups and political parties are critical of Ghar Wapsi, especially when it is done with the state's support, as they say that it threatens freedom of religion in the country.
