Everyone is born into the world entirely ignorant. Cultures, customs, languages, and superstitions espoused by their parents, teachers, and peers are adopted as a matter of survival. And as the individual develops more autonomy, they use the information they gathered in their youth to navigate into new cultures and belief systems, in pursuit of improved material conditions.

You can be born into a Catholic family and become Atheist just as easily as you can be born into an Atheist family and become Catholic. What has driven the modern collapse in religiosity is - at least in my view - the mass migration driven by economic expansion and ecological collapse. People aren't just waking up one day and deciding they aren't gullible anymore. They're being shuffled around by tidal forces and torn away from the historical cultures and infrastructure that had reproduced their families' beliefs.

As a kid, my mom was deeply Catholic and tried to get us to attend church. But we moved several times, and after each move we found ourselves at a new church (often not even a Catholic church) with an alien congregation and divergent dogma. So what had rooted her and her sisters and parents and grandparents in Catholicism never took root with me or my sister.

By contrast, my wife's family lived in Galveston for four generations. Virtually her entire family is devote practicing Catholics. She only slipped through the cracks because... her dad moved around a lot, particularly after her parents got divorced. Everyone else - even two of her transgender cousins - are still practicing. Churches are, at their heart, social institutions. And I think modern New Atheists often miss that fact in their quest to Own The Dumb Pious Folks.
