Once people start mentioning being an atheist casually, as merely one facet of their lives and not their defining characteristic, you know that it has become mainstream.
In fact, it has reached a stage that I get surprised only when I hear writers and artists and other intellectuals mention that they are religious, even mildly so. I do not explicitly seek out atheist writers, so the fact that I encounter so few religious ones must mean something. At the very least, it may signify that the intellectual class as a whole is abandoning religion.
