This is awesome. But there's another solution... Hell, as portrayed by churches, is nonsense. All the spiritual but not religious people have that figured out on some level.

According to his own book which declares it was written by him to show how awesome he is.
Hid knowledge so that he could be the only special one who has it.
Punished people who weren't born until thousands of years later because 2 people wanted to learn.
Murdered all but 8 living humans.
Firebombed 2 cities killing everyone for doing sex wrong.
Declared the guy who offered his own daughter to be gangraped "just" and worthy of saving.
All powerful but repeatedly chooses mass murder as punishment over using his power to just stop the thing he doesn't like.
Denied everyone bacon rather than teaching them to cook it to well done.
We aren't even half way through the old testament here.
If this god is real he is a villain not worthy of worship. Christians are abused housewives begging to have their abuser back.
If I ever came to believe in the supernatural again it wouldn't be to become a member of any branch of worshipping that false god.
Have you found any version of gnosticism yet? Cuz you're not the first to have noticed these things.
Most of those stories are allegorical. You'd have to know the meaning of the symbols for it to make any sense. The problem is, the religion selects for "true believers," as does any organization. The more crazy, the more they prove they're true believers. Antifa is the same. Or any organization where the game is about getting power. This process leads away from truth and principles. The goal posts are always receding, and qualifying as a member of the organization requires passing ever more absurd purity tests, and the organization benefits by losing the members who aren't crazy enough because crazy core can do crazier things. Its an Antichrist version of self sacrifice, exactly the same as the tearful adoring crowds that used to gather in Red Square.
Any of those things you referenced can be explained rationally and symbolically. Verrrrry few people inside of the religion can do that, though, because their presence in the religion is proof that they are irrational -- but not for the reasons usually given by atheists.
This is basically the original reason for Christianity, this decay of previous religion. It is truly meant to repudiate Judaism and correct its errors, **_not imitate them._** This is why I say most Christians are actually Jews, and I don't say that with any malice towards Jews, its just a fact.
I know my position about the judeochristian god being a false idol is common in esoterica.
The issue from where I sit is gnostics and esoterica have supernatural beliefs and I don't. If I came to believe in the supernatural tomorrow that's where I'm most likely to land in the world of religion.
I find interesting insights and morals in Judeo-Christian texts. I can say the same about Odin's quest for wisdom in Norse lore. I'm more hesitant to discuss any of the value of any of Judeo christian text because people have been propagandized their entire life to take those things literally and seriously leading to ruin for them. When I talk about the morals in Odin's story or other things generally accepted as fiction I take less risk of leading people to lunacy.
You aren't the first to notice that group beliefs tend towards extremism, this formalizes the idea well.
