Under the rubric of derogatory terms: what is the value of a term like "cult," which serves no other purpose than to demonise its target?

On another forum, an LDS participant from this board claimed that he had been told that the term "LDS Christian" was regarded as "derogatory" or in some way offensive, and should therefore not be used, because the board administrators hold that Mormonism is not Christian.

Is that correct?

Granted that this is the position of the board, why must Latter-day Saint followers of Jesus of Nazareth tacitly ***ent to what they rightly view as a canard in order to participate here?
