No doubt the average christfag is convinced that he has the right god, the one true god. 99.9% of these people will have never examined any other faith in depth.
Has it ever occurred to you, humble christfag, that people of other faiths, in other countries, in different eras, worshipping thousands of different gods, were all just as convinced as you are that their favourite god(s) were the genuine article, and that all other gods (like yours) were nothing more than quaint myths?
Further, did it ever occur to you that you are all correct about each other's gods and wrong about your own? That they are all crap?
