I was talking to a youngster today, and he explained to me that your choice of religion should be based on how various deities have delivered on their promises, rather like politicians.
Now Jesus promised to bring peace to the world. He has now had 2000 years to deliver on his promise and manifestly failed.
Thor however promised (and I suspect this information comes more from an X box game than from genuine mythology) to rid the world of Ice Trolls.
Now, when did you last see one of those?
