This is an insightful observation.
I was raised Catholic as well, stopped going to Mass when I left home in my early 20s, and just never missed it. As a child I think I believed but as an adult religious belief seems completely unnecessary.
My son, who was raised an atheist, is now deeply religious—he’s a Benedictine monk (no, we didn’t see that coming!)—but even when visiting him religion seems like a lot of nonsense to me. (He’s happy and we accept his choice despite not sharing his beliefs.)
