Yes, it is an undeveloped idea here, but christianity (and communism too) indeed needs poverty and despair to spread out. Christianity can't bear ethnic pride, but they target the poorest and desperate individuals to convert them with a promise of a new moral hierarchy where the poor is supposedly the most virtuous, and will be rewarded by eternal peace and glory for having suffered in this life.
So even if they succeed on some individuals, the main conversion of India is a big fail for their ethnocidal religion, compared to where they had been able to convert by the sword. It is the main reason they want to remove this people out of the twisted vision of the world they give to the westerners through the media. Thank you !
