Welcome @CoffeeBean!!
I am a former Christian myself. I would also recommend the book “God is not great” by Christopher Hitchens.
For me I became much more active by coming here and writing my own book after sitting with some of my Christian friends and they were discussing that demons were why pedophiles existed. I asked them how they measured demons and they looked at me like I was the crazy one… At least here in the US, these people are using their fairy tales as justification to try to stuff their crap down our throats. All while falsely claiming that we are doing it through CRT, SEL, etc, which they can’t even define let alone understand. The more fundamentalists we can de-program, the better it will be for society as a whole.
