I'm flabbergasted Holland even did that interview and allowed those questions to be asked.
I'd like to watch the entire interview, if it's available. I'll look around.
No, Holland isn't a dodo, if by that you imply a lack of intelligence. Mormonism is not an IQ test, and neither are most other religions. My IQ wasn't any different as a TBM than it is now as an apostate, I merely know certain things I didn't know then, and have adjusted my attitude toward evidence, and have made certain decisions with respect to how I will approach the evidence. Also, certain underlying principles in my worldview that color how I see things have changed.
When Holland says dumb stuff about the Book of Abraham, it's not because he's stupid. It's because he believes the Book of Abraham is really true, and therefore he is willing to shrug off the question if he doesn't know the answer to it, with faith that maybe someday we'll know, or whatever.
I think the "dodo" aspect is in how poorly he came off in the interview, not in his underlying intelligence. He comes off as a dodo because the interviewer says "people say Mormonism is like Scientology only smarter" and he responds with "I went to a good school so we're not a cult" (paraphrasing). The accusation being made is that Mormons are weird and culty and Holland in the interview comes off as weird and culty.
