Only if you redefine "religion" into meaninglessness. There is no consistent atheist position on the cause, nature or purpose of the universe. You get everything from nihilism to Buddhism to indifference.
I don't think nihilism, Buddhism or indifference have positions on the origin or the purpose of the universe, so I am not sure their positions are inconsistent. In fact I would say they are consistent in focusing elsewhere.
And Buddhism is often considered a religion so the ground is already muddy. Of course some Buddhists are theists, but not all.
I did try to make it clear I was focusing on a subset of atheists, ones who do tend to share a set of beliefs in scientific methology and 'Reason' - big R but also citation marks to show I have questions about it.
What you're referring to isn't atheism as such, but some conflation of methodological naturalism and metaphysical naturalism. There are plenty of theists that subscribe to the former, and who would be outraged to hear you assert that they're members of some other, ill-defined atheist "religion." Metaphysical naturalism gets closer to what a lot of atheists exhibit, at least in the West, but still isn't the same thing as atheism as such. Plenty of atheists believe in supernatural entities; just not deities.
Sure, plenty of atheist believe in things like a persistent self or a non-embodied reason and other such supernatural entities. I doubt many atheist believe in what are traditionally seen as supernatural entities, at least not the subset I was referring to and the ones relevent to these kinds of online discussions. I mean it is, I am quite sure, true that 'out there' atheists are very diverse, but in here, in these discussions, there is generally common worldview amongst atheists. And this extends to the popular atheist writers right now. The particular argument, online, between atheists and theists represents, mainly, two groups, the particular subset of atheists I mentioned above and Abrahamic theists. There are exceptions of course. But we have two groups with methodologies and metaphysical entities and so on. And I think it is fair to call both religions, at least from where I stand, a pagan on the sidelines. In fact it is what they share that stands out: faith in something transcendent - God or reason - and a mechanistic relations to and understanding of whatever is not human.
Theists come in a pretty wide grouping also and most of them do not fit a lot of the criticisms aim at the Abrahamic groups. And when they refer to the problems that religions cause you can see they are primarily or only talking about a subset.
The dialogue takes predictable forms precisely because two common approaches are crashing into each other. Two sets of beliefs.
These are not perfect sets, but what are on the sociological levels?
