Rightism needs to separate itself from Christianity. There is no reason the two should be intertwined, and this association between the two is one of the reasons sympathizers for Rightist causes are hard to come by. Especially because the Christian religion is false - like all other religions - is why Rightism must act at this moment and part with Christianity.
Let us post historical inaccuracies, literary oddities, anachronisms, mistranslations, and errors that very much show the Bible to be the work of humans, and without divine or even supernatural inspiration:
-The Binding of Isaac: A number of scholars believe that the original story ended with Abraham sacrificing Isaac, and that the ending where Isaac is spared and a ram delivered is a later addition. Old Testament scholar Terence Fretheim wrote that 'the text bears no specific mark of being a polemic against child sacrifice'. Even further, a genealogical snippet immediately after the binding of Isaac story hints at Isaac being sacrificed. First of all, the description of a rash of newborns placed right after the main story suggests the existence of some direct cause-effect connection between the two. From the perspective of a sacrificial economy, such a numerous progeny could not have been conceived without the preceding payment in an appropriate "currency". Even the names of these newborns seem to be a 'code', as they are not proper names: Re’umah (ראומה) – "see what"; Tevah (טבח) – "slaughtering" or "slaughtered"; Gaham (גחם) – "flame" or "burning"; Tahash (תחש) – "skin" often used to cover the tabernacle; Ma‘akah (מעכה) – "blown" or "crushed. In other words, "somebody had been blown, slaughtered, put on the tabernacle and burned."
-Existence of the Davidic Kingdom: There is no evidence of a United Monarchy, no evidence of a capital in Jerusalem or of any coherent, unified political force that dominated Palestine, let alone an empire of the size the legends describe. There is no evidence for the existence of kings named Saul, David or Solomon; nor do we have evidence for any temple at Jerusalem in this early period. Culturally, the Bronze Age collapse is otherwise a period of general cultural impoverishment of the whole Levantine region, None of the conquests of David nor Solomon are mentioned in contemporary histories. Solomon's empire is even said to have stretched from the Euphrates in the north to the Red Sea in the south; it would have required a large commitment of men and arms and a high level of organization to conquer, subdue, and govern this area. But there is little to no archaeological evidence of Jerusalem being a sufficiently large city in the 10th century BCE, and Judah seems to be sparsely settled in that time period.
-The Book of Samuel: The account features too many anachronisms to have been a contemporary source, such as: later armor (1 Samuel 17:4–7, 38–39; 25:13), use of camels (1 Samuel 30:17), and cavalry (as distinct from chariotry) (1 Samuel 13:5, 2 Samuel 1:6), iron picks and axes (as though they were common) (2 Samuel 12:31), sophisticated siege techniques (2 Samuel 20:15). There is a gargantuan troop (2 Samuel 17:1), a battle with 20,000 casualties (2 Samuel 18:7), and a reference to Kushite paramilitary and servants, clearly giving evidence of a date in which Kushites were common, after the 26th Dynasty of Egypt, the period of the last quarter of the 8th century BCE. Also regarded as myth due to its account of warring with the Canaanites, since the consensus today is that the Israelites emerged as an off-shoot of Canaanites in a relatively peaceful (uneventful) process.
