Yes, Glenster, of course the boastful tales of the Israelites exterminating entire nations of people with few or no casualties to themselves are fictions. Their writings that claim some god ordered them to commit genocide are also fiction. Their descriptions of a vengeful god are also fiction...
How much more do Christians need before they can admit that the OT is largely a fiction; the god it describes is not the one they want to worship; and they abandon their stance that the OT is "inspired by God"?
If I keep a journal, and in an early entry I write:
God is vengeful, jealous, and angry: quick to punish the wrongdoer, and punishes his decendants down to the third or fourth generation. He loves the smell of burning flesh, and will only forgive sins if you slaughter an animal. He also wants us to butcher the children of our enemies without mercy.
And then 10 years later I write:
God is love. He overflows with undeserved loving kindness, is quick to forgive, cares about every little sparrow, loves little children, and wants mercy, not sacrifice. He also wants us to love our enemies. And he never changes.
You might say I "progressed in my faith" or something like that. But if you agreed with my more recent journal entry you couldn't honestly say that my 10 year-old entry was "inspired by God". Why would God inspire me (or anyone) to depict him the opposite of what we now believe him to be? It doesn't make sense. If the more recent journal entry is correct then the old one wasn't correct; it did not depict the same god in any sense. (Personally I'd say neither was correct, but I'm trying to depict the Christian stance here and show its inconsistency.) Why does anyone believe these opposite depictions of their god when they are found in the Bible?
If Christians want any semblance of consistency they need to dump the OT. They still have problems after that, but I can't see why they would want to keep this albatross around their neck.
