For me it has been a journey through these books: "Crisis of Conscience", "In Search of Christian Freedom", "Combatting Cult Mind Control", "Releasing the Bonds", "I'm Perfect You're Doomed", "Confessions of a Teenage Jesus Jerk", "Evolution for Dummies", "The God Delusion", "God is Not Great", and "The End of Faith", along with various books about Zen philosophy.
These movies have also been important: "Religulous" and "Worlds Apart".
Some books I am interested in reading next are "The Spanking Room", "Growing Up in Mama's Club", and "1984". Who has read these? Do you recommend them?
What else has been of help to you?
