There's many reasons someone who describes as atheist might become religious. Most people who label themselves as atheists that write books and people who search for knowledge are a minority, the majority of atheists are probably not well represented by populations like AF or TTA and will not be as smart as we think. I think cultural factors might lead people to convert, and some will simply identify as such because it is part of their culture but they might not believe much. Others will miss the community factor religion brings. Another reason might simply be because your life sucks and you want to stick with a higher force because it makes you feel better.

Whoever fights monsters should see to it that in the process he does not become a monster. And if you gaze long enough into an abyss, the abyss will gaze back into you
