True or false?
Most atheists' beliefs are so much a part of them that they barely speak about it and infrequently even think of it.
This differs from ex-cultist atheists who tend to be more emotional about it because the topic pushes their buttons (i.e., this forum's atheists are far from being a representative sample of atheists in the world-at-large and sweeping conclusions about all atheists cannot be accurately drawn from us).
There are a few rabid atheists with no cult background and an affinity for Internet forums who do talk/think about it constantly, but they're the vocal minority.
