There is a story that is touted as true here in N.ireland that a priest picks up a couple of hitch hikers and they are chatting , He asks them what religion they are, and they say that they are atheist . He thinks for a while and then asks" Would that be protestant atheist or catholic atheist?"
The book "The God Delusion" is on my nightstand now. I have to finish the current book first. Interesting how the tensions in Ireland came down to that, another failure of xianity.
