Atheism, like many other
beliefs, undergoes social and cultural selection pressure in a way that
resembles biological evolution. If atheism is taken to simply mean a lack of
belief in God, then there is little about it to hold external interest. So, a
slightly more interesting version developed into a positive view that there is
no God, and with all of the subsidiary counter-apologetics and Promethean
fantasies about a semi-utopian post-faith world of science, reason and
rationality (especially in the past 50 years, where technological advancements
have given rise to unprecedented, improved living standards, and greater global
connectivity).
But these are superficial anticipations based on shallow considerations – nothing of the sort has happened or will happen. Quite the opposite, in fact; the attempted erosion of the Christian faith has created a deeply unsatisfactory void; a kind of spiritual vacuum that has left people discontent and spiritually hungry, where substitutes brought in to fill the void have shown themselves to be intellectually hollow, spiritually empty, morally inadequate, and an assault on many of the long-standing metaphysical qualities (like truth, facts, knowledge, freedom, purpose, meaning and wisdom) that form the bedrock of our Judaeo-Christian-Aristotelian culture.
Consequently, because atheism fails to provide the solution to the deepest and most profound human needs and desires, it becomes less and less interesting the more it persists - to the point where, for most of its loudest and most strident commentators, it’s really become an ideological and spiritual wasteland left in the hands of cynical, myopic individuals who seek attention and validation, and whose primary way of making atheism seem compelling is to lash out at religious belief with dismissive resentment, mockery and scorn. And the more the atheists sense in desperation that what they have to offer is not very interesting anymore, the more resentful, mocking and scornful their comments become in order to grab the attention and conceal the mediocrity of their arguments, all in the service of trying to stay relevant and interesting.
