I don't understand How can somebody be compelled to join a Religion. If and only if ??? the person is convinced then he accepts the other Religion. Stop Blaberring, let me tell you the reason for presence of Islam in India. 1) Sufism, the Mystical way of understanding the Almighty. 2) Caste system which prevailed in Hinduism is the main reason for people attracted towards Islam which is Egalatarian. 3) Giziya Tax for the Unbeleivers is based on the assumption that all the Muslims should give Zakaaat (Charity for Poor)which is the Fourth Basic Pillar of Islam.. Suppose if all the Muslims in India are compelled to accept Hinduism then what will happen ??? People will hate Hinduism and will not accept it at any cost. Same condition applies for all the Religions?? You can never win the Heart of a Man by Compulsion
