Why did god always want my candy money on Sundays. Why doesn't he make his own money since he is all powerful.

Probably the dishonesty of it all. All religion creates an environment that prevents rational questioning of ideas, You are in no way encouraged to question the existence of whichever god or gods you are supposed to beleive in. I can't help but care about the truth as opposed to caring about what I would want to be true. They are two very different ways of thinking. Having said that I must admit that there is no part of me that really wants god to exist or not, I am just interested at looking at the evidence for and against

How it made me doubt and belittle myself.

While I was religious, detesting anything about it wasn't allowed. Like questioning, it was a sin. But now, looking back, I hated, most of all, the feelings of guilt.

I thought I found just that when i started going to a Pentecostal church with my first wife. All that speaking in tongues and prophesizing. Scared the crap out of me. I thought I had finally found where the truth was.... I really hate those preachers. Damn lying assholes.. they're really good at screwing up your head

Being expected to 'obey', 'obey, and 'obey' some more; all without thinking.
