Let us stay focused on the Cult of Mormonism.

I will leave you to that! I was 14 when I picked up The Book of Mormon lying on a library table. I've always been interested in any account of God, and the first thing I read was to pray over whether this was for me. Then I skipped ahead to the first actual chapter. I was disappointed. It sounded like it had been written by a 14-year-old boy. In later years, I heard that it had been! But, the book said I should pray about this, and in favor of prayer, I did just that. The answer was clear.
This is not for you. I have always focused on that final word, 'you'. My prayer was not answered with the word, "anyone". it specified me.
I had/have faith that the Holy Spirit of God can work through anyone. I believe God can even work through a con man, also a pedophile. But it wasn't for me. As an adult, I heard people speak of them with disdain, as a joke--patronizing. Through my grandparents, I had been deep into genealogy since I was ten. I was particularly interested in their stories. I have Quaker ancestors who have a different view of the Sacrament of Baptism than I. I respected their outlook, and as a child was amazed and disturbed that someone had had them baptized after their death! Such disrespect!!! Treasuring my own baptism, I considered this proxy "baptism" a blasphemy against the power of the Holy Spirit in my ancestor's view of what baptism is/means.
As you aptly put it, I saw those proxy "baptisms" as reducing Baptism to an admission ticket to the LDS vision of an afterlife instead of a sign and purpose of learning to live Kingdom Living, walking with God, in this fallen world. For LDS to dismiss The Way of Kingdom Living which starts
Eternal Life right here in favor of putting their words into my mouth at a time I cannot speak directly to them is not only wrong, but vilely wrong. LDS should listen to how Quakers view baptism. They should listen to how I, a Catholic, view baptism. LDS may see baptism as some kind of an admission ticket, but many-many of us do not.
I will not be able to speak then. Therefore I speak to them now. Will they listen? (Not so far, and I've been at this for years.)
