It is funny that many non-religious people see religion as more inflexible than religious people. They ask fundamentalist questions and then complain when they get fundamentalist answers.
I think that comes from Protestantism actually. Smaller and more cohesive than Catholicism, and motivated by concrete theological disagreements, it could get away with being doctrinaire. Catholicism, in contrast, may have been a big target for discontents, but it was a slippery one; a shifting big tent with internal divisions and as many ideas of what it means to be a catholic as there were bishops. Messy. Occasionally sloppy. Occasionally pragmatic. Moribund with inertia and a need to at least publicly acknowledge the pope. But because of its relative vastness, it was difficult pin down when it comes to actually conducting the theological debate sought by the Protestants.
Following a millennium of Catholic stagnation, Protestantism was sharp, focussed, easily explained. The primary criterion for adherence was a willingness to consider that this central messy compromising authority of the papacy might be wrong. It required asking for specifics.
In that regard, I consider Protestantism a gateway drug for Atheism. It left a cultural imprint of questioning authority which permitted the achievements of the enlightenment and all that has followed.

And with a nod to an old story retold by Hitchens, I'm readily able to declare that I'm a protestant atheist. To me, purposes don't matter in the least; discussing the purpose of something is the stupid endeavour while it's not settled whether there even is such a thing. Even more so when there are good reasons to believe it's been made up.
I think you describe a few salient features. I also think your analysis is an extension of all I find to be meaningless in the catholic variety of atheism; the relativism, the anti positivism. Catholic atheism gave us a legacy not of the enlightenment, but of things like homeopathy, and sociology, and "new age" and postmodernist deconstructionism, and "spiritual journeys" and "self-actualization" and even all the sorts of things that were so successfully lampooned in the Sokal Affair.
"Meaning" and "self realisation" are just the kinds of trifling details that fall into place once you know what's actually going on in the universe.
So I do accept the notion of atheism being somehow fundamentalist, at least protestant atheism. And at least the fundamentalists agree on the importance of the questions, if not the answers or the methodology to reach them. But unless you'd like to dismiss all of protestantism as being non-religious, then you don't have a monopoly on defining what religion is.
Finally, I think it will be interesting to see if Wahabbism gives rise to its own strain of atheism. I suspect it will, and I suspect it will more closely resemble the protestant atheism of northern european origin rather than the relativist sort from the south.
Religion is about spiritual growth, maturity, self-realisation. Non-religious people seem to think it is all about making assertions about reality. They ask stupid questions like "what is the proof that God exists?" rather than "What is the purpose of belief in God?".
I don't believe that it is any accident that many truly religious people are gay.
I guess that many of us on this forum were confused about our sexuality when growing up. In spite of the contradictions between our biological sexuality and our main role models and expectations of society, we came to the realisation after all that we are gay. We made one big step towards realising who we are. We have a head start.
But if you don't think that is a step on the path of spiritual growth or self-realisation and if you don't think that has got anything to do with the purpose of religion, then you have no idea what religion is.
