LDS is a non-Christian cult. A non-Christian cult is an organization that claims to be Christian while at the same time denying core teachings of Christianity. One such core teaching is that there is one God. Mormons teach that there are many gods and that human beings can become gods, create their own worlds, populate them and "save" them if necessary.
LDS isn't merely "different." It is a non-Christian religion that masquerades as a Christian religion, using Christian terminology, slogans, and some Christianesque ceremonies.
Tearful "apologies" do nothing to establish LDS as Christian any more than using Christian vocabulary.
