My point is simply that if you claim that it is not 100% accurate then the decision about which parts you choose to rely on as historical and which you dismiss ends up being arbitrary and subjective.
Not always.
You study the text for information you need, and do not take it as so, and even for scholars there is no guarantee. BUT in many cases there is no dispute and it is not subjective.
More often then not there is what is plausible academically, and what is refused by apologetic bias. Im not accusing anyone yet, but assuming the "text" is accurate follows this line most of the time. Or assuming it covers different cultures belonging to one religion that covered a large geographic area.
"they worshipped idols, and the other half says "in Jerusalem" it seems capricious to say "the first half is accurate but the second half isn't." And that's what was being done here
What I am saying is that it is not debated that these multiple authors that redacted the text to monotheism to Yahweh may have viewed others as idol worshippers, but that it did not reflect the majority of the population. They held a partial position.
Geographic location matters not and especially in Jerusalem where multiple cultures gathered.
Around the time of the verse in question before the text evolved "King Josiah" era, monotheism to Yahweh was not well established in all the people. And just because the political decision for the people to become monotheistic, does not mean it even held the majority position.
