First of all I don't believe in preaching one's religion to others. I have got sick to my stomach when few Mormon guys have told me that my Hindu religion is wrong and their religion is right. Nepal is a country infested with casteism. Submarine folks (pani muni ko jaat) like Sarki, Kasai, Damai etc., are looked down by Bahuns/Chettris. Also Nepal is a poor country. So as long as we have this mentality of differentiation by caste & poverty in Nepal, opportunistic crusaders will entice poor people & Submarine folks into becoming Christians. It’s the same anywhere. If you ever visit South India, you will see many South Indian Christians especially in places like Mangalore. If you research their background, they will either come from a poor background or belong to low caste. For many Submarine folks in Nepal, converting into Christianity looks to be the best option since they are sick & tired of being treated badly by the society. Also since Christian missionaries have money, they see a chance to get out of poverty. In my personal opinion, this is a great hazard & divide in our Hindu religion. Tolerance is key.
