Yes indeed.
I was raised a Baptist and was an enthusiastic and devoted believer until I was almost 25 when I had an epiphany. I was trudging along my personal Damascus Road when the clouds of illusion parted and the god of reason stuck his head through and said, "Didge, Didge, why persecutest thou me?"
So I stopped believing in God and my life began afresh from that day. That was more than 50 years ago and I've never regretted it.
But don't think me hidebound. In the four years I spent on Ask I re-converted to the one true faith. I am now a convinced and practising Pastafarian.
R'amen!
