Call me the naive one (or a sinful and willingly 'dead in ignorance' type), but last I went to church was at sixteen. This was around the prime time of questioning as to what I believed and followed and thought that the solution was to head to church after insisting myself weeks prior to it that I'd go. Attended Sunday night mass and left. It wasn't the same anymore. It used to be something that helped me to get through the week even if I didn't know everything about it. The people who attended weren't so bothersome, but there wasn't a connection either.
In a way, I'm glad I was raised in the Catholic church I went to for religion classes and whatnot. It wasn't the best and there were definitely flaws now looking back. But with the way many shun you just because you don't do something they say is what drives one out so quickly. I remember a nun told us that if we didn't attend to every Sunday mass, we would be questioned and ultimately sent to hell. -shrugs-
I've looked into other sections somewhat. Some seem a bit crazier than others, but I'll admit that I'm probably going by stereotype more than anything else.
