Just showing compassion and tolerating other's religion is not like tolerating some one like duryodhana.
The very essence of krishna's teachings lie in the very compassion that he shows unto us.
If krishna is not compassionate, then he wouldn't have given us the bhagavath gita, thus leaving us to stray in this mire of delusion and ignorance of the material world.
we need to show compassion to people who come here especially if they are not of our beliefs, due to the very fact that when they come here they don't tend to be fans of hinduism, when you show disgrace for their religion, then you tend to create disgracement for our religion in their hearts... hope you understand.
Anyway, it is just so funny that even your signature has a question mark when asking a question...
It used to be "jai sri prabhupada!"
now its "jai sri prabhupada?"
