Have I asked this before? Who knows; but what was the defining moment for your that you realized organized religion was BS?
My Moment was when I was thinking about how all the religions seem to be created out of man's fear of death. That realization made all of the religions seem very ridiculous and not particularly relevant. Being willing to face your fears head on seems to be the cure.
Even in my youth I never believed in any fairy tales or Santa Claus or religion, any religion.
My mother, thinking she was doing good, baptized me into the mormon cult, at 8 years old..four years of their lies, bullshit, and abuse, I walked away, never looked back, and over the years, became a complete and total atheist. Today i am repulsed and sicked by the abuse by "DECEIVERS," profiting and abusing "believers..."
It was pretty gradual here too. Listening to comedians like Lewis Black, George Carlin. Listening to philosophers and outspoken atheists like Alan Watts or Penn Jillette. Being passionate about science because of people like Bill Nye and Neil Degrasse Tyson. And reading Chet Raymo’s the soul of the night all had a big impact on unwinding the indoctrination of lies for me and I’m eternally grateful to all of them. The moment I most suddenly became full bore atheist is a long story for another time but I wouldn’t have had the choice if it weren’t for these formative things giving me other ideas as options.
I was 8. They gave us a test in Sunday school and I failed. I was told I was not getting into heaven because God didn't let dummies in. I began studying all religions I came across, not just my parents. From the on I never again took anything on blind faith.
For me, it was a gradual unwinding out of ministry that took years. Dan Barker's "Godless" and Joseph Campbell's "The Power of Myth" were like a scary but welcome gut-punch to my faith-based life. The final straw was a book by Irwin Lutzer "The Doctrines That Divide". This is a well-known and respected Christian theologian who made a circular argument before the end of the first chapter that caused me to shut the book and say, "I'm done. I just can't believe this any more."
