Read it slowly, and whenever you read something fucked up, ask yourself whether an omniscient and omni-benevolent being would act like the god of the Bible acts. Seriously! It sounds simple, but often what is simplest works best.
Read about this dude named Jephthah in the Old Testament. Dude murdered his little daughter as a sacrifice to the god of the Bible. Did the biblical god denounce her murder? Did he punish Jephthah? Did he provide ram for the father to sacrifice in the place of his daughter? Fucked-up story, man.
Read about King David, the dude who was the apple of god's eye. He sent one of his soldiers off to war so that the guy would get killed and King David could fuck the guy's wife. Some hero, huh?
"Well," you may be saying, "that's the Old Testament! Jesus is much kinder in the New Testament!" That's where you're wrong, kiddo!
What happened to Ananias and Sapphira when they withheld a little bit of money from the brand-new Christian church? Those fuckers were struck stone cold dead over withholding tithing! Shit - god sure is a stickler for money! (Acts, chapter 5)
And what about the Prince of Peace himself - Jesus? Well, what's he going to do when he comes back for the sequel (his second coming)? Why, that peaceful motherfucker is going to slaughter millions and millions of unbelievers, according to the book of Revelation. Those Christians sound kinda like ISIS, to tell the truth.
If you read these stories without the little Sunday School voice in the back of your mind telling you that the Bible is full of wisdom and compassion, you'll see for yourself how fucked up that book is.
See? You don't have to read anything other than the Bible itself in order to deprogram yourself. But it does take time. It's taken me years and years.
