Polytheistic claims are false .
Humans assume that all contradictions are false. Any worldview that does not allow for this assumption to be rationally justified is deductively false.
Premise 1: If anyone is not the author of every aspect of creation, then his authority is insufficient to rationally guarantee the behavior of creation.
Premise 2: Under polytheism, no one is the author of every aspect of creation.
Conclusion: Therefore, under polytheism, no one has the authority to rationally guarantee the behavior of creation.
Humans assume that creation is non-contradictory. Under polytheism, there can ultimately be no reason to hold to this assumption, making it an irrational assumption.
This Argument from Reason therefore demonstrates that polytheism is deductively false.

"Isn't it the case that, rather than presupposing god as it claims to, the presuppositional view actually presupposes logic and reason?"
Every human presupposes the possibility of coming to rationally justified conclusions. Presuppositionalists recognize this fact. However, any belief ultimately caused without reason is ultimately held to irrationally. Under most worldviews, all human beliefs are ultimately caused without reason. This demonstrates the irrationality of atheism, polytheism, pantheism, and unitarianism, as well as empiricism.
"Did Jesus preach non-violence? He says in Mat 5:39 Whoever smites thee on thy right cheek offer him the other. But in Luke 22:36 he says He that hath no sword, let him sell his garment and buy one. How then can Heb 1:8-12 says he is unchanging?"
Addressing the last part of your question first, the text is below: Hebrews 1:8-12 (from Psalm 102:25-27) - NASB But of the Son He says, "YOUR THRONE, O GOD, IS FOREVER AND EVER, AND THE RIGHTEOUS SCEPTER IS THE SCEPTER OF HIS KINGDOM. "YOU HAVE LOVED RIGHTEOUSNESS AND HATED LAWLESSNESS; THEREFORE GOD, YOUR GOD, HAS ANOINTED YOU WITH THE OIL OF GLADNESS ABOVE YOUR COMPANIONS.
"If the book of Genesis is not to be taken literally, why did god send himself in human form to die in order to save us from a symbolic sin committed by metaphorical characters (Adam and Eve) who never existed?"
The Apostle Paul compares Jesus to Adam in the book of Romans, chapter 5, verses 12-21, and in such a fashion that if Adam were not a real man, one would have to conclude that Christ were not either. In Luke 3, the "beloved physician" Luke provides a Genealogy of Jesus including his step-father Joseph, King David, his father Jesse, Boaz (husband of Ruth), Judah, Jacob, Isaac, Abraham, Shem, Noah, Seth, and (yes) Adam.
