To challenge a leader of the LDS Church brings certain condemnation and disapproval from God on High.

Let's just ponder this for a second. To even question the motives or the actions of the appointed head of the church automatically puts you in God's bad graces?

God  gave you the ability to reason, to contemplate, debate and think  critically for a reason. If God really is omniscient and omnipresent  wouldn't his word and direction stand up to a little (or a lot of )  honest debate?

But lets consider an honest debate.  Not with the intention of causing controversy or needlessly causing  strife. But with an intention of knowing the truth, in love, with  respect and compassion.

I mean, that's a pretty bold  statement to say you "speak for God". So if Joseph Fielding Smith says  we'd never get to the Moon, and then we do...... what else could he be  wrong about???
