The trick here is that "endless torment" does not really mean being tormented forever into eternity with no end in sight, ever. Its just a way of saying "God's torment" or "God's punishment" because God himself is eternal and "Eternal" or "Endless" is another one of his names.6 Nevertheless, it is not written that there shall be no end to this torment, but it is written endless torment.
7 Again, it is written eternal damnation; wherefore it is more express than other scriptures, that it might work upon the hearts of the children of men, altogether for my name’s glory.
8 Wherefore, I will explain unto you this mystery, for it is meet unto you to know even as mine apostles.
9 I speak unto you that are chosen in this thing, even as one, that you may enter into my rest.
10 For, behold, the mystery of godliness, how great is it! For, behold, I am endless, and the punishment which is given from my hand is endless punishment, for Endless is my name. Wherefore—
11 Eternal punishment is God’s punishment.
12 Endless punishment is God’s punishment.
Fine. Whatever. Mormonism redefines words all the time so why should this be any different.
On the other hand, does this words-have-no-meaning-or-value-at-all thing have wider implications? What about eternal life? Eternal salvation? Eternal families? Are those things still "eternal" in the traditional (real) sense of the word? If so, how do we know? How do we know that the fake eternal only applies to punishment and not reward? If we accept D&C 19 at its face value, then we have no guarantee that anything with respect to the Mormon gospel will last beyond... I don't know when, but certainly not into eternity.
What are we doing this all for again?
