Atheists, agnostics most knowledgeable about religion, survey says - latimes.com
Based on all my online discussions and debates, it does not surprise me. However, one could argue that level of education plays heavily into it, as there is an inverse relationship between education and religiosity.
But more fundamentally, IMHO, I think the more people know about what they believe, especially if they believe in one of the major theologies, the less likely they are to believe it.
There is a certain irony, though, that the people that are most interested in religion are the irreligious. Perhaps it boils down to the fact that those who do not know their opponents arguments, do not completely understand their own.
And that's my arrogance for the day.
