I went to Catholic high school and it turned me into an atheist. Once you get up close to it you might dive in or you might run screaming.
Which comes back to my point about casual Catholicism.
Particularly in the Americas, Latin America. A large chunk of the population is mildly Catholic, to the point where they don't attend church or do half what the Catholic Church commands, but they FEEL Catholic and often have statues of the Virgin Mary everywhere.
American Catholicism is bit different to European Catholicism that why I think. There is a greater emphasis on Mary is a central figure, and of a Mother figure.
I certainly would question sending my kids to an overly Catholic school (and so would the wife for that matter).
As for Atheism -
On Tarot it can be a way to internalise conflict and help make decisions if nothing else so it can have a placebo effect which can be positive if not over invested.
I think most Atheists have an existential crisis at some point. Its impossible not to. But I resolved mine in 2 ways.
The first was admitting there could be something after death. Not necessarily a heaven as written in some book, but *something*. The idea we see family again when we die is comforting so I hold that even if its not a certainty.
The second was seeing humanity as a single organism, evolving over time. This makes the purpose of the species, and my purpose in life by extension, to evolve the species to a higher state, through technology and social improvement, and avoid our society evolving into an evolutionary dead end, IE driving ourselves extinct. We've probably reached the end of biological evolution, at least to any major degree, now we undergo technological and social evolution to gain the power to control every aspect of our universe and maximise our collective happiness and satisfaction.
But as I've said before on the forum I leave the door open for a God/Gods to contact me but I've not seen anything so far, and I can't invest my faith in something I can't feel.
