TLDR version deleted, here’s the synopsis.
I used to suffer from religion. But I cured it. With my BRAIN.
I went to a Pentecostal church for most of my childhood. They’re pretty hard-core fundies; believe in faith healing, speaking in tongues, etc. I questioned beliefs for a long time, even as a kid, though I externally bought into it enough to fit in most of the time. Even went to Bible study and other church activities.
There were no arguments that swayed me, it was simply the accumulation of life-experience and knowledge that showed contradictions to every single core belief they held. The final blows were my mother’s death from breast cancer and subsequent dissolution of my family, and having a best friend who helped me get through what is the absolute worst time in my life to-date turn out to be gay.
Between seeing my mother reduced from one of the most articulate people I knew to a bloated parody of that woman from the masses of brain tumors, and one of the most supportive, caring, unconditionally loving people I’ve ever met being something that the “good people” of the church treated with hate and disgust, the remaining shreds of my faith didn’t really stand a chance.
I went to one more church meeting in college, and found that I rather pitied them because I realized that they needed something I’d outgrown by that time. They would never be self-sufficient even if they stopped going to church and removed themselves from the community aspect of religion, because they internally would always be leaning on the crutch of god.
By that time, I’d gone past my initial reactions of treating god more or less like an abusive parent, to what I now know was a form of atheism. God was simply irrelevant to my life. I knew that I could survive completely without faith.
So, you could say that god convinced me that he didn’t exist. If I hadn’t had the experiences I had, I probably would be a good church-going boy, even though I’ve always been the kind of person who questioned things. Due to a severe crisis in my life, I went from being a bit apathetic about religion to rejecting it completely.
