That's an immensely complicated answer for me. On the one hand, I don't subscribe to any religion per se and you might call me an athiest by some of those measures. On the other hand, in a way I subscribe to all religions because I believe they give you a window in time, culture, and geography for how humans experience the divine. Not necessarily the divine in terms of an old dude with a beard who farts planets. But the divine in a sense of being part of something larger than yourself.
When I was in Mysore a few weeks ago, I got a massive kick out of being inside the Shri Chamundeshwari Hindu temple in the middle of Pongal where all sorts of crazy shit was going on. People inscribing swastikas on a back "wailing" wall with colored bindi dot powders, the odd crush of people to make offerings to the Hindu god statues inside, etc. But the most sublime part for me was when they carried out one of their Hindu idols from the temple out in front on the plaza as a rare thing they do on special occasions, and the worshippers go a little looney over seeing it publicly for the first time in a long while.
Five years ago in Fatima, Portugal, I pretty much witnessed the exact same pageantry in a Catholic ceremony where a statue of the virgin Mary is carried out in the basilica plaza for a rare occasion and all the worshippers go nuts at the rare chance of seeing it, etc. The fact that here you had two totally different religious cultures in two different parts of the world following almost identical practices ties something together about the human experience that can be a bit magical for me.
So while I'm no more athiestic than an agnostic, calling me agnostic isn't quite right either. In Facebook-ese, it's complicated.
