I never disagreed. I simply stated that, for the sake of clarification, it would be better to refer to these groups by their official acranim, FLDS. I would also prefer the original church being refered to as LDS instead of Mormon.
The term Mormon was originally used by the mobs that persecuted the saints. It was meant in a derogatory way. It is very similar in origin to the term NIgger.
I made a simple, and polite, request so that those who do not understand the difference between the groups would not get confused.
