Who are you to say they aren't Mormons. Maybe they say that LDS aren't the true mormons. Who is anybody to say anything about anything?
Are you one of those folks who believe every things is relative therefore there is no wrong?
Specifically, the polygs are not members of the Church of Jesus Christ of Latter-Day Saints.There is no such organization known as the "Mormon Church."
As there is freedom of speech, especially on this Forum, I can and do say quite correctly the polygs are not LDS and not Mormon either.
