Please elucidate where he contradicted himself. At any rate, I thank you for the conversation in general since it has been elucidating as to your ideas and views and at this point I think I will more or less say so long, if you care to answer where you think he contradicts himself exactly that will be ok, I'll look at your statement.
He tried to claim that the Levites were the only tribe in Egypt, which would have been the only tribe in the Exodus, but remember, the Golden Calf incident was part of the Exodus. He brought back the rest of the Hebrews for that:
"The Levites were not people to whom one said “No.” Four different biblical texts connect them to violent acts. Levi is one of the brothers who massacre the city of Shechem for the violation of Dinah (Genesis 34), and he is also cursed for his general violence in Jacob’s deathbed testament (Genesis 49). The Levites slaughter the people associated with the golden calf incident, thus following Moses’ command to put them to the sword (Exodus 32:26–28). And in the poem at the end of the Torah (Deuteronomy 33), God is asked to “pierce Levi’s adversaries’ hips, and those who hate him, so they won’t get up.” These four texts come from four different authors. So basically
everyone knew: You don’t mess with the Levites."
He does not have a clear narrative. He picks and chooses what he wants to believe instead of making one coherent explanation. This would be laughed at if someone tried to publish it in a journal.
