As a child, I was told in no uncertain terms that I had to go to church. Period. Baptized at an early age, I had no idea of it's symbolism. Most of the time in church, the pastors that delivered the sermons were shouting and pounding the pulpit. (To keep us awake, I think)
In Sunday school, I went through the same brainwashing as everyone else, but for some reason, I still retained ideas that were independent of church doctrine. I told myself that there had to be something besides the black & white judgements of the church. I realized that after endless lectures about how everything bad that happened to people was Satan's doing, and anything good was a miracle from God.
No wiggle room, no exceptions. Either you take it on faith that there's a supreme being that watches over us and guides us, and died for our sins, or you're one of the unfortunates who will burn in hell for eternity.
In my Baptist family, there was no coming out as an Atheist. If that word was even mentioned, shocked horror was the reaction. But once I had moved away from home, I was free to believe or in my case, disbelieve what I wanted.
To this day I don't initiate a conversation about religion with any family members unless they bring it up. The one time that happened, my sister sensed something in my attitude and asked me if I believed that, "Jesus Christ was my lord and savior". To which I replied, "No." She then told me that she felt she had went wrong somewhere and it was her fault that I was an Atheist.
One truth I have learned is that some religions would not continue as a viable force in the world without the use of guilt.
