Gee says he's upset that LDS critics do not engage with the content of the Book of Abraham. But then in the next breath, he states why this is the case: That critics find the text of the Book of Abraham to be inaccurate and therefore not worth discussion.The critics really don't get into the content of the Book of Abraham. They don't read it carefully, and in some cases don't read it at all. And a lot of them just dismiss it as not being historically authentic, so they don't need to test it. And so if you eliminate the text from consideration, then the only sort of discussion point that you get is the translation issue.
It's a clever rhetorical trick if you are not paying careful attention. He's right that critics view the Smith "translation" as pseudepigrapha, but then declines to actually make the case that the text is true. It's a a sleight of hand trick to shift the burden of proof from the side making fantastical and unsupported claims to anyone who would disagree. It's also a form of a "Gish Gallop" in which the apologist claims (truly or falsely) that unaddressed claims are, by default, true.
As Shulem has noted in his Celestial thread regarding the king's name, the content is actually the weakest point in the Book of Abraham apologetic case. I'll add to this thread periodically to look at specific verses.
Edit to add: Needless to say, Gee is actually lying when he says critics have not discussed the content of the Book of Abraham. They have many times, and he knows that they have.
