I guess I'm kind of lucky in that I never really "experienced" God, so not only was that part of the reason I ended up becoming an atheist, but I didn't have any problems with the idea that I once felt God, so I knew he was real. I did believe he was real, but after looking at things critically I realized I was just fooling myself. Of course, I was raised Catholic instead of in one of the more charismatic churches where you're trained to have a "personal relationship with God." In the Catholic church, you're taught to more or less go through the priest to get to God.
Christian apologetics is the art of rolling a dog turd in sugar and selling it as a donut.
