Like hell there isn't! To belong to any atheist community, you need to align with their dogma, have read and agree with their favorite authors, and "other thingamajigs" or you'll be ousted as a troll or worse.
Can I make a guess? You're American, aren't you?
Can I just point out that American Atheists are, uh, weird? They are not representative of 99% of the worlds Atheists.
I once met a nice girl, who had just moved to the UK from America. She told me that on her first few weeks here she wondered where all the atheists were, and it took her to little while to figure out that unlike the states, atheists did not seek out other atheists, congregate into groups, and spend all their free time discussing atheism. In fact it was quite a relief to her when she realised that atheists were everywhere but as nobody a) gave a shit b) talked about religion or lack thereof, she could just relax and go about her day without interference or having to form Atheist Defence Leagues.
For the record. Myself, personally, as a life long atheist, have never read Dawkins (because that's who you meant, isn't it?) and think he's actually a gigantic cock. I've never knowingly been a member of an "atheist community" (do they build Yurts?) and I really don't care if other atheists can agree on anything, or even if they're having pitched battles in the fucking streets. The only "dogma" I'm aware of is the rather good Kevin Smith film.
You are right about one thing: as an atheist it's not just "lack of belief in God". It's also a lack of giving a shit what you or other people think, or caring when you project your own biases and religious frameworks in a desperate attempt to make sense of it. You're wrong and I simply don't care.
