New atheism is an informal social movement in which atheists have become more vocal and publicly prominent in the 21st Century. This may be in part as a reaction to the 9/11 attacks and increasing religious extremism. The movement has been largely centred around the best selling publications by Atheist authors, including Sam Harris, Christopher Hitchens and Richard Dawkins.
After the 9/11 attacks, there was renewed interest in books that blamed social problems and terrorism on religion.  The movement is characterised by an unwillingness to remain silent in order to get along with theists. The previous conciliatory attitude, many believe, prevents atheists' voice from being heard in the political and social arena. This has led to some backlash, from both religious and secular quarters, claiming that such outspokenness is perceived as confrontational and hurts the acceptance of atheism. The influential publications in the movement include:
- The End of Faith, Sam Harris, 2004
- Breaking the Spell, Daniel Dennett, 2006
- The God Delusion, Richard Dawkins, 2006
- God Is Not Great, Christopher Hitchens, 2007
- Against All Gods, A C Grayling, 2007
- God: the Failed Hypothesis, Victor Stenger, 2007
It is a matter of some debate whether the term "new atheism" should even exist. There has been no philosophical revolution in recent years; the arguments used by atheists today are not radically different from ones used in past decades and centuries. However, the recent books have been updated to reflect current events and are written in a more accessible style than the original philosophical works. It may be that publishers and TV producers have been more willing to give atheists a platform rather than any shift in the debate. 
The Internet has also enabled the movement to be debated. This has been accompanies by the rise of Internet celebrities in many blogs, youtube channels and podcasts. There have also been TV series with similar themes and hosted by the celebrity authors, such as Root of All Evil? with Richard Dawkins and the documentary The God Who Wasn't There.
New atheism has no unified manifesto, no central authority or organisational structure, no definite beginning, and no obvious cause. For this reason, it is difficult to identify the defining ideas of the movement.
Questioning religious privilege
One common idea in the new atheism is that religion has enjoyed a privileged position in public discourse: that one does not criticize religion in the same way that one might criticize a movie, a philosophy, or a political movement. People like Richard Dawkins and Sam Harris have argued that this respect is undeserved, and that religious assertions must be subjected to the same scrutiny as any other assertion of fact. As a result, Dawkins is often accused of being "shrill" or angry, while others believe he is merely being forthright.
In a similar vein, in Breaking the Spell, Daniel Dennett argues that religion can and should be studied like any other phenomenon; not in the sense of theology, but rather the psychology, sociology, neurology, anthropology, etc. of religion.
Promoting acceptance of atheism
Few prominent atheists believe that religion can be completely eliminated any time soon, or that there will ever be a time when a majority of people count themselves as atheists.
However, religious figures have always portrayed atheism as undesirable, if not downright evil and immoral. The new atheism seeks to increase public acceptance of atheism, in the same way that the gay rights movement seeks to gain public acceptance of homosexuality.
Prominent atheists all seem to endorse rational thinking and science as the best way to know about the world (as opposed to intuition, for example). However, there has long been significant overlap between rationalism and atheism, so this is not something new to the new atheism, but rather a continuation of earlier themes.
New atheism has laid many societal problems, such as terrorism, bigotry, discrimination and totalitarianism, directly at the feet of religion.
Accusations of fundamentalism
After debating with Sam Harris  and Christopher Hitchens , in May 2008, Chris Hedges wrote a book I Don’t Believe in Atheists (2008) based on the experience. He criticised the new atheists for offering a delusional "Utopian belief system", scientism and their modernist idea of the moral process in mankind. He claims new atheism ideas are inadvertently helping a neo-conservative agenda by promoting the same foundational doctrines of moral superiority and utopianism. He criticised some new atheism proponents for attempting to justify pre-emptive war and torture in extreme circumstances. Hedges expressed concern that anti-Islamic forces, drawing support from both the secular movement and the Christian right, could possibly result in a "call for a horrific bloodletting and apocalyptic acts of terror". 
Various commentators have echoed Hedge's view and cited fears of cultural bias or discrimination against religion, including Pope Benedict XVI,  Baroness Warsi of the UK government,  Alister McGrath,  and theologians Jeffrey Robbins and Christopher Rodkey.  This criticism has been generally dismissed by the new atheism movement.  Often what the New Atheists regard as the removal of religious privilege in society and government, the religious interpret as discrimination.
Poor supporting arguments
The prominent books of the movement have been criticised as shallow, poorly written, "Incurious, dogmatic, rambling and self-contradictory",  having little understanding of what they are criticising,  selective use of history , more theatre than scholarship,  and the books have had little impact of belief.
