A place where ModDB members can debate civilly, and learn from each other's views.
To which my answer is a simple "yes" and this is based on what constitutes to as a religion.
Religion (contrary to pop culture belief) is simply a set of codes or beliefs. Super-naturalism and gods needn't be involved. This is the case for Buddhism (which can be apathetic or atheistic) and Cārvāka.
Fundamentally, atheism is no religion. The average atheist you meet at work probably isn't religious but many of the "new" atheists (especially the ones you'll encounter on the internet) have a religious devotion to everything materialistic in philosophy. They have gatherings, forums, social events and even speak on agreed upon "rational" principles and their view of what skepticism is. Often they use the same arguments from atheist philosophers of the past and many have the same common goal of bitterly attacking religions and religious people.
This religiosity has extended so far that atheists have now opened a church named The Sunday Assembly (http://sundayassembly.com/) which is established in 30 cities across the world. There are others such as the "First Church of Atheism" and mega-atheist churches.
These places allow for gatherings of atheists and the non-religious (although most seem to be atheist) to benefit from the social practices of a church without any worship involved.
This form of atheism certainly is a religion. Even without churches involved, many of the "new" atheists follow the trend of attacking religion and religious people whilst preaching their materialistic world-view.
