Is it a "100 page hit piece" or is it a "multi-page critique?"
We may never know. I think we should immediately censor all "critiques" in the world. That way, no one will have their feelings hurt.
You seem to think that you have caught mormonstories making inconsistent statements about the document. You are either disingenuously pretending to misunderstand, or you really don't grasp the point of using the second description, rather than the first, in a question to DCP. You seem articulate enough that I would be surprised if you weren't being disingenuous, rather than just dumb, but I suppose everybody has lapses in judgment.
Nevertheless, I'll spell it out. When asking a question of somebody with an incentive to be evasive, it is important to phrase the question as broadly as possible, so they can't use the specificity of the question to say "no," when the answer is actually "yes." In this case, the phrase "multi-page critique" is broader than the phrase "100 page hit piece," and therefore covers more possible descriptions and perceptions of the document, which makes an evasive answer more difficult to pull off.
As an illustration, if the document is actually an 87 page document that DCP wouldn't personally characterize as a "hit piece", then asking him if he wrote, specifically, a "100 page hit piece" would result in a "no" from DCP, even though the document attacking Dehlin really does exist, in virtually the form the questioner suspects. Asking him, however, if there is a "multi-page critique" would more accurately describe this document, and force DCP to answer with a "yes." This all assumes that DCP is telling the truth. The phrasing of the question is irrelevant if the answerer is willing to lie.
(I would even say that the second phrase isn't broad enough to avoid an evasive answer.)
There isn't a conflict between those two phrases in the context in which mormonstories has used them, and you haven't scored a rhetorical point. Does that make sense to you now?
