whats the biggest reason you left christianity?

Besides sending me to Sunday school for a few years out of a vague sense of Catholic guilt/duty, my father never really pushed Catholicism onto my brother and I (my mom was a nominal English Anglican, but really didn't give a shit about it). We moved to many different countries while my brother and I were growing up, so our religious 'education' kind of just fell apart. The strictest it got was around my dad's family, many of whom were still strict Catholics besides a rogue aunt who went Baptist to please her Georgia husband (my dad himself was one of 10, and his mom had a handful of miscarriages because she barely spent a year without trying to have children).

With the rather lax environment of religion at home (we even stopped going to church after I was about 10 - it just became a boring family hassle), combined with the fact that I was lucky enough to attend good schools which encouraged high levels of critical thinking, plus that I had access to a lot of literature from all sides of the argument, I just kind of found my way out on my own. Considering the arguments, looking at the evidence for a proposition versus the lack thereof for others.

Still strange to see the shadows of indoctrination in my dad though. Whenever we travel and go through a Catholic church to look at the art and architecture, he still does the hand signs and dips his hand in the water and yadda yadda, and he's still instinctively resistant to criticism of the Catholic church, despite the fact that he doesn't believe any of it anymore.
