This is not quite the same comparison.
The Church of Jesus Christ of Latter-day Saints IS a specific organization. Christian does NOT denote a specific organization.
Fundamentalist Mormons do not want to be known as Mormons. They want to be knows as a break away or protestants of the Church of Jesus Christ of Latter-day Saints. The biggest issue being they want to live Polygamy.
Currently, a polygamist is immediately excommunicated from the Mormon Church.
But "Christian" isn't quite as nebulous as you and others have stretched it to mean. A "Christian" is literally a "Christ one" -- one who belongs to the true Jesus Christ.
First of all, it can't just be any "Christ"...and secondly, just because Christian doesn't denote a specific organization does NOT mean that "Christian" doesn't involve a specific ORGANISM -- that organism being the Living Body of Christ. LDSism is tied to one organization; Christian is tied to one organism.

Well, now you're just playin' with words. fLDS have the "LDS" part of their name for a reason! Even if fLDS don't want the "moniker" of "Mormon," doesn't mean they want to discard "LDS."

No they don't. I mean, yes, they want to distinguish themselves from mainstream LDSism, but, no, they don't want to break away from the identity of being a "Latter-day Saint." As a matter of fact, because no LDS leader has ever dumped Doctrine & Covenants 132, the fLDS actually see themselves as "originalists" in terms of following Joseph Smith.

Well, now in one sense, you're arguing in a circle. On the one hand, DieHard the Hunter says...
...that if you say a Mormon is not a Christian, that it's unkind, unnecessary and un-Christian...
...but then when I point out that if you apply the same standard to LDS, that for them to label fLDS as not "Latter-day Saints" would likewise be unkind, unnecessary, and un-Mormon...
...you point out actions fLDS do that cause LDS to label fLDS as "ex-communicative"
So...based upon this, please explain something to me here: Why do you think it's "OK" for LDS to label fLDS as outright heretics for having many or more than one wife, yet seemingly...
...some FREEPERS here don't see anything heresy-wise about LDS having many or more than one god.
Why is polygamy such a "hot-button" issue that gives LDS full-blown permission to be "unkind" toward fLDS -- but polytheism isn't regarded with equal weight & concern?

(Not if they live in the LDS "celestial kingdom"...and not if they're around when the Mormon Jesus returns...as LDS apostle Bruce R. McConkie promised in his book, "Mormon Doctrine" that Jesus' return would then reinstute the "holy practice" -- "holy practice" being his words)
