Even though this is bit of a long read, it looks like the initial part of his argument is trying to give the old tried and true "we don't have the scrolls", so you can't disprove the BOA. So just shut up and move along. Argument.
Claim #1 - Out of the four scrolls in Joseph Smith’s Egyptian collection, we know that Joseph Smith used the missing Amenhotep scroll as his basis for the Book of Abraham text, based on witness descriptions.1
Even though I think there are plenty of arguments to engage in this position. We do have facsimile #1. It and facsimile 3 are traditionally contained in scrolls just like the ones that we do have in church custody. The BOA actually talks about facsimile #1 being connected to the text being translated. etc.
But I don't think that is even the big point, so I am not sure whether or not it would be worth arguing about. Because we do have all of the facsimile's with Joseph's translations. And none of it is accurate. Even when apologists try and make a bullseye, you have to do it standing on your toes and squinting. Joseph clearly had zero ability to translate. Which is verifiable with what we do have and we don't have to chase down elusive lost long scrolls as the source.
And then we should push back on his approach of intentionally holding back. Here is his advice about not making too many strong statements because too much detail opens them up for being shown a fraud. To me, this advice smacks of an intention for deception and just wanting to be right. Instead of wanting to find the truth.
Claim #2 - There is a good reason missionaries don’t like to delve into “deep” subjects like Kolob and Adam-God Theory. It is because there is so much speculation out there, so much falsehood pushed by fake Mormons, and so much we simply don’t know. It is dangerous to take a solid position because the slightest falsehood can lead to huge misconceptions. It makes an opponent so much easier to tear you down when you trying to support a lot of weak positions. The (false) claim that Joseph Smith used the seer stones to translate the gold plates can lead to a hundred other skeptical concerns, and suddenly faith in the Book of Mormon becomes untenable.
Finally, his true colors come out in his advice #13.
Advice #13 - Feel Free To Ridicule Antimormons
If I had a family member trying to use this guys research to support the BOA, I would stick at home on these areas and not get lost in the wall of words trying to distract from the main truths.
1) What we do have does not reflect a real and true translation of Egyptian into english.
2) The text of the BOA could not have been written by Abraham and be a direct translation because it contains anachronishsm that Abraham would never have known.
Abraham 1:1 Starts with "In the land of the Chaldeans, at the residence of my fathers, I, Abraham, saw that it was needful for me to obtain another place of residence;"
Here is the problem. The chaldeans didn't exist as a people until about the year 1,000 BC until 600 BC. Well after the life of Abraham.

The reason Joseph picked up the people chaldeans, is because it is found in the bible in context with Abraham. But this is a known and natorious anachronism in the bible as well.

Good luck.
The more words people use, I find that more they are trying to take a simple argument and make it so complicated, that people will just give up and walk away.
But we have the truth on our side and should never feel bullied by people like this.
