The so-called new atheist movement has mostly died out, however, atheism, and other non-religious views, are continuing to grow. Atheists and other “nones” (those that don’t identify with any religion) are largely disorganized, in that they do not belong to communities or groups that may help represent their interests. This article explains why I believe new atheism, and other atheist movements, have failed to inspire mass affiliation and change minds.

The main mistake of the New Atheist movement, in my view, is that its leading proponents gave off the impression that they considered atheism to be a sufficient substitute for religion (except for Sam Harris, who is trying to build a movement for rational spirituality). Their vision of Utopia seemed to be one in which an educated, rational, and mostly atheistic populace would behave prosocially and with stoic equanimity in creating a world without religious conflict, war, bigotry, hunger, and poverty. This simply is not a psychological reality in our current world.
Atheism offers nothing to replace the ethical, practical, and existential framework that religion provides. It is simply an absence of belief in deities. And the stillborn “atheism plus” movement only offered simplistic “woke” virtue signaling, and the divisive / indignant condemnation of others that is characteristic of these new secular social justice movements — rather than a psychologically informed and philosophically grounded theory of social justice (see SJWs the New Moralists).
Although it may sound pessimistic, I don’t believe we are close to seeing dogmatic religion, and the conflict it inspires, disappear from the world. Realistically, there are many people that need the restraint and scaffolding of religion to act prosocially, and to cope with the existential problems entailed by the human condition. Some societies may collapse without this scaffolding (see Does Religion Increase Moral Behavior?).
Religion also offers benefits in the form of ethical and practical instruction, and a possible community to belong to. While some alternatives to religion (e.g., Humanism, modern Epicureanism or Stoicism, secular Buddhism) also provide these benefits, these worldviews or life philosophies are either too vague (for instance, Humanism) or not well known / developed — in addition to having few, if any, established communities outside of the internet.
Many intellectually sophisticated individuals can lead healthy, acceptably prosocial, and happy lives without religion, but the global community is not ready to give up the opium of the masses, nor would the world necessarily be in better shape if they did — at this point in time. It seems highly plausible that some people need the carrot and stick of religion to stay out of habitual antisocial behavior — on the individual and collective level — and to assuage their existential malaise.
In order to reach something approximating an atheistic Utopia, there are many changes that need to be made in education, reproduction, and our socioeconomic systems, etc., but perhaps most importantly, we need to further build alternatives to religion — such as those mentioned above (see Why It Is Important to Have a Philosophy Of Life).
