YES! There's a huge sense of freedom and relief in letting go of the belief in God that I was raised with - it's refreshing to not feel like I'm being judged and I'll never be good enough. I mean, I'm pretty great, if I do say so myself. Why would I want to spend my time and energy in a place with people who make me feel like I'll never be good enough?
Re. the voices - my educational background is in psychology and I work part-time as a psychometrist in a day hospital for adults with schizophrenia. "Hearing voices from otherworldly folks" just screams "undiagnosed mental illness" to me, but I understand that's likely just due to where I come from in life. After that, I think about how George W. Bush claimed that god spoke to him and, well... we know how well that turned out.
