Your half baked knowledge is commendable. The Vatican folks are not interested in what Christian missionaries do in India. Catholics and 'new Christians' are different. Prolific Christian evangelism is supported wholeheartedly by US and UK.. People forget that Hinduism is an idealogy and a way of life that is open to different interpretations, unlike other institutionalised religions, which are rigid. It will dwindle as the newer generations pay lesser attention to old text and families disintegrate.
