Mormon apologists for the most part, will never believe a killer blow can exist. Pacman over at FAIR said this exact thing when someone asked the TBMs what kind of evidence could there be to dissuade them from the Church's truth claims. He said point blank, "no amount of evidence." He was later compelled to go back and remove it because it was so telling. It pretty much proved the apologetic position was not grounded in reason. It was grounded in feelings. Nothing concrete that we know we know can get in the way of what a TBM feels he knows.
DCP knew this would appear intellectually bankrupt so he offered some unlikely scenario. He said if an affidavit were uncovered signed by Joseph Smith, which said the LDS Church was just a prank the whole time, then that would be enough to convince him. But I don't believe an authenticated statement like this would really do the trick. He would probably rationalize how Satan had temporarily been able to take hold of the "Prophet" in order to test the future saints. He would dedicate a dozen FARMS reviewers to tackle the subject for at least a decade while waiting to "find out all the facts" before drawing the obvious conclusion.
DCP, and myself, have a testimony; a direct spiritual witness, though the power of the Holy Spirit,of the truth of these matters. You do not. Hence, you are not qualified, in any manner, intellectually or otherwise, to pontificate on what apologists think or understand regarding the Gospel. Do you get it Dartagnon,
you are not qualified to make the distinctions and conceive the central points. You have painted yourself into a little box in which you have only your very limited, fragile, and biased intellect to help you make sense of it all. This, of course, will fail, as intellect alone is a poor, poor substitute for revelation and direct perception.
You're fired Dartagnon, you are not qualified. Burger king is hiring...
