Good poem, I've heard it a few times already.
Now why should the largest religion in the world (Christianity) come here and try to kill off existing belief systems like Buddhism/Taoism/Confucianism by saying me and my family are "pagans" who will burn in Hell for the rest of eternity?
If I went to some guy's face and said he and his family would be tortured for all eternity, well I would get into a bloody fight wouldn't I?
Luckily no one wants to hit a missionary/priest/monk, so they get away with it. But it is still incredibly rude, do I go to other people's countries and tell them their Gods are fake and that they and their families will burn in Hell for all eternity?
Any common courtesy or even common sense?
