Ask a deeply religious Christian if he'd rather live next to a bearded Muslim that may or may not be plotting a terror attack, or an atheist that may or may not show him how to set up a wireless network in his house. On the scale of prejudice, atheists don't seem so bad lately.
I came to the conclusion long ago that all religions were true and that also that all had some error in them, and while I hold by my own religion, I should hold other religions as dear as Hinduism. So we can only pray, if we were Hindus, not that a Christian should become a Hindu; but our innermost prayer should be that a Hindu should become a better Hindu, a Muslim a better Muslim, and a Christian a better Christian.
Whether one is Hindu or a Muslim or a Christian, how you live your life is proof that you are or not fully His. We cannot condemn or judge or pass words that will hurt people. We don't know in what way God is appearing to that soul and what God is drawing that soul to; therefor, who are we to condemn anybody?
