Can There Be An Atheist Agenda?

After I got into a disagreement about tactics with John Loftus of Debunking Christianity, I ended up in a discussion of what, if anything, an atheist agenda should consist of and whether atheists had anything at all in common beside their disbelief in God.

First, the posts dealing directly with my dispute with Loftus

Want to help write a book? — Loftus solicits possible questions for a Christian apologist and I offer a few thoughts
Why do atheists ask the boring questions? — Loftus’s questions turned out to focus on biblical inerrancy rather than philosophy, and I am disappointed
My Problem with Loftus (Part 1) — Why I disagree with Loftus’s focus on evangelicals
My Problem with Loftus (Part 2) — Atheism isn’t interesting or compelling unless we go beyond tearing down religion
Loftus responds to my critique — Neither of us is satisfied by the other’s agenda

After that discussion ended, I responded to commenter questions about whether it is valid to treat atheism as a cohesive movement:

Are Atheists a ‘Side?’ — If atheism is a belief with no clear consequences, what does it mean to call someone a ‘bad atheist?’
Why I Treat Atheism as a Team — Atheists, as a stigmatized group, need to work together
Are People ‘Atheists First?’ — Is your non-religious belief central to your life and/or identity?
