Preach, I understand and respect your position; it is, of course, a matter of faith (blind or seeing) in the end. That being said--and in keeping with the subject of this thread--I see only a few real
questions here. I may have to address them one at a time.
1) Do we believe that God feels anger? Was he angry with Joseph Smith?
I'm not sure what scriptures you would cite to support your claim that he doesn't; I could offer several more (mostly from the Old Testament) that say that he does. But religion isn't a card game--"I'll see your apostle and raise you a disciple and a prophet." The real truth in the matter would have to come from the synthesis of two or more scriptures on the topic. Here's one to support God getting angry:
Ex. 4: 14 And the anger of the LORD was kindled against Moses, and he said, Is not Aaron the Levite thy brother? I know that he can speak well. And also, behold, he cometh forth to meet thee: and when he seeth thee, he will be glad in his heart.
And here's one to refute:
1 John 4:7 Beloved, let us love one another: for love is of God; and every one that loveth is born of God, and knoweth God.
8 He that loveth not knoweth not God; for God is love.
So assuming that both of these are true, how can they not contradict each other? There are many interpretations, but here's one: God feels a deep disappointment when we squander our potential on dust. Like any parent, he wants the best for his children, and sometimes he chastens his children. This can sometimes be interpreted as anger (especially by the children, who often don't fully understand) but in reality it's an espression of love. This synthesis of love and chastening is well expressed in Isaiah:
27 For the fitches are not threshed with a threshing instrument, neither is a cart wheel turned about upon the cummin; but the fitches are beaten out with a staff, and the cummin with a rod.
28 Bread corn is bruised; because he will not ever be threshing it, nor break it with the wheel of his cart, nor bruise it with his horsemen.
29 This also cometh forth from the LORD of hosts, which is wonderful in counsel, and excellent in working.
In other words, chastening from the Lord is according to the individual strength of the person receiving it. The Lord's anger at Moses (and, by comparison, with Joseph Smith), was merely a chastening so that Joseph could improve. And Joseph learned the lesson: he couldn't put another man's counsel above the guidance of the Lord. In this case, the chastening was perfectly suited to the person being chastened.
