Perhaps it’s only because I’ve seen such a small sample of your writing about Mormons, but it appears to me that you feel all Mormons are like those. I won’t deny there are some like that, even far too many. You appear deeply hurt by them, and that seems to color your response to all. How would (or does) your family feel about the way you talk about Mormons here? Why does someone who obviously did not properly follow Mormon doctrine, which you must be at least somewhat familiar with, have so much negative effect on your beliefs?
We had problems with one of our former bishops, here. Just because he was a jerk doesn’t mean the Church is untrue. My feeling on him is that he was made a bishop to drive home certain lessons to him, as well as to us. I won’t claim infallibility on this one, either, it’s just my personal opinion. One thing it did not do is shake my faith in the Church. That particular bishop, yes. Maybe even those who set up apart as the bishop, a bit. They are also those who removed him, too, so maybe he disappointed them, as well. I left my ward because of him, and waited a goodly while to return after he left. I’ve even forgiven him. I don’t think he deliberately did what he did, I just think he was a volunteer.
You are taught by your church to think of me this way. My Christian fellows don't think I am hurt, or bitter unjustly. When someone is led to believe an untruth, and all the accompanying jumping through hoop to earn exaltation, and they discover the simple truth of Christianity, then I'll agree, they might appear (to Mormons) to be bitter.
I wish you could come to Church with me. I think you would learn a great deal.
