I know, it’s as though Mormons live in a buble. They can’t take or refute criticism of any kind. Almost as though you’d have to be blindly loyal before you get the truth, as opposed to the truth reinforcing your loyalty. It’s no wonder that so many Christians consider LDS to be cult-like.
Just about any one else would engage in logical debate, correcting or refuting another’s errors, as Our Lord Jesus Christ did throughout His Gospel. Jews, Protestants, Jehovah’s Witnesses, et al. preach. Mormons clam up. It’s very bizarre to someone who enjoys learning, which I do.
