Hinduism is secular which does allow freedom of worship, but that does not mean it enforces you to stick with only one form of god worship. It allows you to choose, propagate, and convert if you would want to both out of the faith and to the faith. That is what secularism is all about. Ghar wapsi scheme exists because there is no restriction on moving from one religion to another in India. Did not say all religions are equal and neither does Hinduism consider all religions equal. We understand some are down right stupid, but they are given the right to be stupid as long as they stay within the limits of the law of the land.
