I posted for a while on Randi.org, but events of late have made me a bit peevish about public displays of religious affection - I do have some experience with these sorts of forums and am probably more at home someplace like Atheists/Agnostics or Science than Religion or General Discussion, from what I've seen thus far. I've used this site as a news resource for a while, along with ThinkProgress, TPM, and some others.
I pretty much agree with your definition of agnosticism. I have thought of myself as an agnostic Christian for a the last few years as I sorted out what I read once I went beyond the canonical and started reading some of the extant contemporaneous texts of Judaic and Christian apocrypha (from the DSS to the mountains of Kabbalistic commentary out there). What do I even mean by that? I suppose that I don't know if I think Jesus was divine, anymore. I kind of think maybe the Council of Nice went the wrong way.
Sometimes I'm not even sure, on reading some of the more sensationalistic, but very early, pseudo-Christian texts, if it's right be so certain that Jesus was even human. Then I read Newton's extracurricular writings and he doubted that Jesus was either divine OR human.
So I'm in a state of suspended animation on the subject, until I learn more. I suppose I was never antagonistic to atheism (my mom is agnostic, my dad an atheist) so it's just a journey I'm on at the moment, to see for myself if there's cause to believe, and if so, what that belief would look like. I suppose I'm more comfortable with atheists than true-believers, however, just because of upbringing.
So thanks for the Welcome to A&A, and there's my "Hi my name is Aaron Dahl and I have no clue!"
