I don't identify as an atheist anymore. I don't think I have for a while.
Since my identity as an atheist was just that -- an identity, not a set of arguments I could muster -- I don't think this is a shocking shift. I became an atheist as a teenager as a reaction to the hateful and irrational behavior and beliefs of every theist I met, and I have ceased to identify as an atheist due to the cockiness and anti-philosophical bent of contemporary atheist culture.
These sorts of shifts are interesting, especially as someone who claims to be invested in constructing belief systems reasonably. None of the important shift in my life have been on the basis of reason, or at least not primarily. Or rather, there are two tracks of my personality: what I identify as (no longer an atheist) and what I know (enough to get myself into trouble). This works for my politics also: I live on a commune not because I have some solid arguments I can bring to bear about communitarianism, but because I find the cultural contact stimulating -- I've grown more as a person and a thinker by being in contact with radical politics, and I've grown more as a person and a thinker by being in contact with theists.
So, I think there is something reasonable about this identity shift: I place a high value on not mentally stagnating, and atheism was precisely that. Encountering thoughtful theists over the past five years or so has been the sole reason I am humble instead of cocky. And probably, by proxy, the main reason I'm not a libertarian. Eesh.
I don't know that I identify as anything with regard to god. Hopefully I will again, one day, and hopefully on the basis of something more than an identity crisis.
