Mentally, it was when the $4,000 fine article from the San Diego Reader popped up on my news feed and I started investigation the child abuse that this religion was responsible for covering up.
Emotionally, a couple of weeks after the above, I watched a video on the vestigial traits that humans have because of evolution. There was one that talked about how our ears have muscles that cause them to "perk up" or move at a sudden sound. I have always wondered about this because my ears do it. I would ask other people I knew well if their ears did this; I thought it was strange. Come to find out that there is no other reason our ears do this other than we descended from a species for which this was necessary during their hunting days. I wanted to cry when I saw that video. It seems like such a small thing, but it was such a simple, sensical answer to this tiny thing I had wondered about myself.
