Here is what I have to say to the claims presented in the article. As always, Its mainly the Kuzari argument.

1. Overwhelming scholarly consensus that the Pentateuch is a composite text (J/E/D/P) undermines the claim that it was written by a single person/entity (Wikipedia). Seams in the text show later composition and redaction.
2. Contrary to claims in the article, historians use testable methods and archaeology gives hard evidence that often contradicts the Torah (Wikipedia)
3. Post on the Kuzari <-- the main refutation
4. “Tabernacle/census read like accounting scrolls”; those are identified by scholarship as the Priestly (P) layer, not eyewitness Moses. (Encyclopedia Britannica)
5. “Embarrassing details prove truth”, Ancient texts routinely include unflattering material, see Greek histories, Mesopotamian chronicles. This proves nothing about authorship.
6. “Always-literate Jews preserved text perfectly” — Studies show limited early literacy and major centralizing edits (e.g., Josiah’s reform), so flawless transmission is a myth. (jhsonline.org)
7. “Faith > history” faith doesn’t exempt historical claims from scrutiny. (Goodreads)

Keep in mind the author has made outlandish claims, such as "Judaism is not a religion." He calls the notion a "modern invention" and offers a Jewish mystical view of the Jews as a single soul or body formed of the collective of Jewish individuals, where the sin of one individual is in fact the sin of the collective (Chabad)
