I personally prefer the metaphor to (say) a 'University' or 'PerlKnights' or something.
I also prefer that view of this site, as it seems to be a more apt view considering that learning is such a central theme.
In any case, I'm an atheist (but some of my ideas are agnostic in nature) and find religion a very interesting topic to talk about with people, such as why they believe what they do. I also like to learn about and discuss the various religions of the world. Luckily for me, most of my friends (whose beliefs consist of Christianity, Judaism, and Islam) don't mind discussing religion at all, probably because we are all respectful of each other's beliefs.
As for affecting my code and posts here on PM, my beliefs really don't affect them.
