I suspect a lot of her "discoveries" are spoon-fed confirmation bias and square peg-round hole "facts". I know there have been several RfM threads about how the Nephites conspicuously do NOT follow the Mosaic law, or at least don't talk about it, in the New World.
I say this with no Hebrew knowledge but lots of JS was a con-man knowledge. :-)
She doesn't understand that Joseph plagiarized most of what is known as the BoM.
He also studied under a Hebrew scholar who was a dentist/Mormon convert who traveled with the Mormon pioneer wagon train to take up residency in Salt Lake City following Smith's assassination.
Practically everything in the BoM was copied from other sources. Since it wasn't an original work or source, the things she cites that bear resemblance to Jewish traditions are what was taken verbatim from the King James Bible, &/or the oral and written traditions the Hebrew scholar was instructing him in up until Joseph's death.
For a Jew to convert to Mormonism is like checking her brain at the doorway to the church entrance. She says she's still a Jew in thought, but she hasn't done her research or she would know Mormonism as the farce that it is.
Jewish theology is vigorous on questioning its own beliefs. In Mormonism there is virtually no thought process other than accepting whatever one is instructed to believe and then put up and shut up. No questions allowed beyond the script that's in the instruction manual.
It is not a religion for deep thinkers or questioning minds.
It is a pseudo religion at best, and pure cultism at its worst.
