You know, Joseph Smith copied many, many chapters from the prophet Isaiah into the Book of Mormon (italics and all...italic words were words the KJV translators added in the 17th century to words not in original Hebrew text). Because these were word for word, we get the picture that the so-called Mormon "prophets" of lore (and I emphasize Lore as in "myth") trusted the prophet Isaiah down to every word.
Were the God of the Bible "clearly polytheistic" then both those "prophets" of BoM lore -- as well as Smith in the JST -- should have re-edited the book of Isaiah to the following "specs" so that your polytheistic Gods could be superimposed upon Isaiah:
So, I've done you the "courtesy" to have your current or next "prophet" change these verses in the Bible (just like what Joseph Smith thought he had the authority to do) to read as follows:
* "I am the Lord, and there are others; apart from me there are multiples of gods." (A perversion of Is. 45:5)
* "I am the Lord, who has organized all things, who with a council of gods stretched out the heavens, who spread out the earth with my fellow divine family members." (A twisting of Is. 44:24)
* "It is us who made the earth, and created mankind upon it. Our own hands stretched out the heavens; we marshaled their starry hosts." (A pretzel version of Is. 45:12)
* "I am the first, well almost, and I am certainly not the last; there are other gods all around me." (More twisting - this time of Is. 44:6)
*"Did I not proclaim this and foretell it long ago? You are our witnesses. Are there gods beside me? Yes, I know plenty." (Utter perversion of Is. 44:8)
*"Before me generations of gods were formed, and so shall it be evermore happily ever after." (Ah, again, the Mormon "gospel" twisted version of Is. 43:10)
May I "sweetly" challenge Lds to go to the Bible they say they adhere to and meditate day and night upon Isaiah 43, Isaiah 44, and Isaiah 45? Isaiah reminds us, as if the above verses weren't enough, in 45:14: "'Surely God is with you, and there is no other; there is no other god.'"
Indeed, show us in the bible that there are other true 'gods' besides God, mormons.
