Is atheism a belief?

[Angrboda]

Let me rephrase your questions, and maybe you'll see how they fail...

Please describe the belief all theists have in common.
Please sum up the theist *ideology* all theists have in common.
What doctrine do all theists have in common?
What theory do all theists have in common?
What system do all theists in common?

You mean besides the belief that a god exists? I think you're disproving your own point here, Huggy. Atheists are no more united by a belief beyond the absence of gods than theists are by the presence of them. Specific sub-groups of theists, on the other hand, do have beliefs that form systems and ideologies. Atheists, too, form sub-groups, just to a much more limited extent. As the old saying goes, trying to get atheists to agree on something is like herding cats. This is so because, generally, atheists are all going in different directions.

Like the definition of faith and religion, this is simply another exercise in, "If I can't have mine then you're not going to have yours either." It's fundamentally hostile and motivated by theist concerns, not legitimate atheist concerns.
