HB you are incorrect. lds practice polygamy in Arizona, Utah and Nevada (probably other states as well) they follow Joseph Smith’s teachings and mormonism as it was first written.
In addition, what you do think all these “celestial marriages” are? They are polygamist marriages for their own godhood, plants.
Polygamy is practiced in mormonism everyday.
Lds "prophet" Lorenzo Snow is infamous for developing this couplet -- which explains Mormons being god-wannabes:
"As man is, God once was; and as God is, man may become."
P-Marlowe, years ago, applied this couplet to Flds vs. Lds in a thread many years ago.
Last year, I applied it to polygamy in a tagline I had for a while:
Tenses of polygamy: "As fLDS now are, LDS once were. As fLDS now are, LDS may become."
So, allow me to explain that:
As the Flds now are (earthly-speaking) -- polygamists -- Lds once were; As the Flds now are (earthly-speaking) -- polygamists -- Lds may become (upon death -- or, upon the Mormon Jesus returning to earth).
You see,
#1...We've got McConkie's prophesy about polygamy coming back to earth...
#2...Brigham Young prophesied that he "will have wives and children by the million" (Journal of Discourses, Vol. 8, p. 178)...
...and his First President (3rd-ranking Mormon of that time), Heber C. Kimball, who had 45 earthly wives, said: ...we will go to brother Joseph and say, "Here we are brother Joseph; we are here ourselves are we not, with none of the property we possessed in our probationary state, not even the rings on our fingers?" He will say to us, "Come along, my boys, we will give you a good suit of clothes. Where are your wives?" "They are back yonder; they would not follow us." "Never mind," says Joseph, "Here are thousands, have all you want" (Journal of Discourses, vol. 4, p. 209).

#3...I mentioned in a previous post three Lds current "apostles" who have been sealed to two wives in the Mormon temple "for eternity"...they expect, upon death, to become eternal polygamists.
