It seems that DCP, Kwaku, Hamlin are done- no prominent Mormons are left to debate anyone. They can't defend their positions and won't engage outside of carefully controlled terms (like belittling Gemli in the SeN comment section). So missionaries are thrown to the wolves with 4 years of high school "seminary" as their training to defend the church.
At the beginning of the video, the missionaries can't even answer a simple question about 1Nep 10:
What is the Book of Mormon talking about here? They hem and haw and realize it can't mean what it plainly says."And he said unto me: Behold there are save two churches only; the one is the church of the Lamb of God, and the bother is the church of the devil; wherefore, whoso belongeth not to the church of the Lamb of God belongeth to that great church, which is the mother of abominations; and she is the whore of all the earth."
What follows is 40 minutes of excruciating back and forth as the missionaries realize their church makes no sense and the answer is always "we just believe."
At the end, it appears an LDS adult comes to rescue the poor kids.
Why won't DCP or some other prominent LDS adult actually defend the church? Why is the church feeding kids fresh out of high school to the spiritual wolves, with no good answers to defend themselves?
