Although I am disinclined to continue engaging with semantical and definitional ambiguities, the following may perhaps, be of interest.
From Sherlock’s references
From:
“The Evolution of Atheism: The Politics of a Modern Movement:”
(The link provided was to a review of the book)
“The Evolution of Atheism” is marred by significant historical, analytic, and conceptual errors, to say nothing of a ponderous postmodern style all too familiar in the social sciences today. Try this turgid passage on for size: “The analysis in this book offers a picture of a movement confounded in its attempts to define itself by a complex and sometimes self-contradictory set of discourses, and of groups of people united only by their lack of faith struggling to maintain cohesion in the face of deep divisions in their politics.”
“As for the errors, they permeate LeDrew’s book. They include an incorrect definition of atheism, a contradictory view of the New Atheism, a disturbing lack of historical understanding, and an underlying hubris that encourages the author to jump to conclusions instead of admitting when he lacks information.”
From:
“Growing criticism by atheists of the New Atheism movement”
“Can Science Explain Religion? : The Cognitive Science Debate”
(this is a rant by a professor of religion which attempts to define “New Atheists” as militants with an ideological movement responsible for increases in Islamophobia. It refers heavily to the prior book, “The Evolution of Atheism” but rather than recognizing the flaws in the book, this diatribe paints a picture of a militant movement with a social and political agenda, harkening to the conspiracy craziness rampant on the internet.)
(from the book)
“Stephen LeDrew’s The Evolution of Atheism shows that atheism is not just the denial of belief in God but is itself a system of belief in a “secular ideology” with a particular cultural and political agenda, an agenda powered by a simplistic view of science and a rationalistic utopianism that “exhibits some totalitarian tendencies with respect to the use of power.”
From
“Is Atheism a cult?”
“While we noted that a cult doesn’t have to be religious, atheism isn’t a unified movement of non-religious people. While all atheists agree that there are no gods, most atheists come to that conclusion independently. There are also many different kinds of atheists: implicit atheists, Christian atheists, weak atheists and strong atheists to name a few. This lack of ideological purity or unified structure runs counter to the idea that atheism is a cult.”
From “Why there is an atheist movement”
“But how can there be a movement around not believing in gods? Easily. It happens when people who do not believe in gods face discrimination and bigotry because they do not believe in gods. The atheist movement is about promoting atheism and celebrating the atheist part of one’s identity. It is about protecting atheist civil rights. It is about combating anti-atheist bigotry.”

Then from “finally”
This is a Wikipedia article concerning secular movements , making no mention of atheism as a movement.
None of the references identify atheism as a movement, even the ones which do identify an atheist movement
