I addressed this nonsense back on an Oct. 31 FR thread.
On that thread, I cited ex-Mormon Latayne Colvett Scott's 1979 book, The Mormon Mirage: A Former Mormon Tells Why She Left the Church (Zondervan)
On p. 194, Scott highlights the assembly-line like process teens like her would be used for in these Mormon temple proxy baptisms...note the bold-faced portion below:
"When my name was called, I went down into the water. The baptizing elder turned me around so that he could see a large screen, something like an electric football scoreboard, which he looked at over my shoulder. On top of the screen was my name, and below it a name I don't remember, but which I'll say was Elizabeth Anderson. 'Sister Celeste Latayne Colvett,' he said, looking at the screen, 'having been commissioned of Jesus Christ, I baptize you, for and in behalf of Elizabeth Anderson, who is dead, in the name of the Father, and of the Son, and of the Holy Ghost. Amen.' Then he quickly dropped his right arm from the square and lowered me beneath the water. As I was regaining my footing (you learn after the third or fourth time to put one foot slightly behind the other to help you get back out of the water) he had already begun the same prayer, inserting this time the name of another dead woman which had flashed onto the screen behind me. Fifteen consecutive baptisms were performed with me as proxy in a matter of about three minutes. As I left the font, another proxy was preparing to be baptized. Then I was led into a 'confirmation room' where a man sat on a high stool with a chair near his knees. I sat on the chair, my back to him, and he and several other elders placed heir hands heavily upon my head while he pronounced this prayer: 'Sister Celeste Latayne Colvett, in the name of Jesus Christ, we lay our hands upon your head for and in behalf of Elizabeth Anderson, who is dead, and confirm you a member of the Church of Jesus Christ of Latter-day Saints..." (The Mormon Mirage, p. 194)
What's of significant interest in the "confirmation room" process Scott wrote about is that many Mormons have said that this proxy Baptism process offers a "choice" in which spirits on the other can reject becoming Mormons. Yet, an "automatic" confirmation process into accepted membership in the Church has been part and parcel of the proxy baptisms--indeed Lds leaders "confirm" dead souls as "members of the church."
I mean, what? You Mormons have a "living prophet" who supposedly hears EVERYTHING the Lord does (Mormons oft' miscite Amos 3:7 to prove that) -- and yet you don't know about "rejections" of the Mormon proxy baptisms on the other side of the veil in the Spirit world? Your "fast-food" like assembly-line baptismal flows are just automated membership processes?
