The "new atheists" label tends to be used on these anglo contemporary atheists intellectuals. I have read them and tend to agree with them on some things. On the other hand their views have been used by liberals for justification of "humanitarian intervention" by NATO powers againts muslim countries and movements since, from a particular liberal irreligious reasoning, those things are undemocratic and "oppressive of women" and western countries are paradises of freedom of expression and, well "freedoms" in general.
If someone wants to find an argument similar in its contemporary atheism to that of the anglo New Atheists but coming from a non-liberal anarchist perspective, better check Michel Onfray´s "Atheist Maniesto" (see http://en.wikipedia.org/wiki/Michel_Onfray
). Onfray is aware of Stirner and declares himself a "leftist Nietzschetian" and so it comes more as philosophical atheism instead of the anglo liberal "New Atheists" who do it from ultra rationalist, scientistic and liberal perspectives.
On the other hand i am an advocate of freethought (http://en.wikipedia.org/wiki/Freethought
) and anti-religious activism. This particularly for countries like the USA where religion is an important form of political manipulation and where religious institutions do have an important influence in public opinions. This has been a constant within anarchism and was advocated by important anarchists theorists such as Emma Goldman, Mikhail Bakunin and Sebastian Faure.
Now an anarchist atheist reasoning is going to be different from a liberal reasoning. As such here is a nice compilation of anarchist atheists texts:
Some nice texts to consider include:
Mikhail Bakunin. "God and the State". http://theanarchistlibrary.org/library/michail-bakunin-god-and-the-state
Emma Goldman. "The Philosophy of Atheism" http://theanarchistlibrary.org/library/emma-goldman-the-philosophy-of-atheism
Sébastien Faure. "Does God Exist?: Twelve Proofs of the Nonexistence of God
A more contemporary one and an interesting one since it also distances itself from scientism and ultrarationalism while embracing a freethought position which also criticizes recent cults of New Age and other origins.
