I can only speak for what is recorded in Church History
And the platform Joseph ran on.
The trouble started after Joseph Was Killed it seems this Zevedee Coltrin had something to do with the change.
Did this Zevedee Coltrin write the Book of Mormon? As the OP said:
As well intended as the latest words on the official church website are, they can affect no real change in policy or teachings because these scriptures remain. Why call these scriptures racist? The definition of racist is the belief that some races of people are better than others because of their race, their skin color. This is precisely what the LDS scriptures STILL teach. Here are few examples just from the Book of Mormon:
Alma 3:6 And the skins of the Lamanites were dark, according to the mark which was set upon their fathers, which was a curse upon them because of their transgression and their rebellion against their brethren
3 Nephi 2:15 And their curse was taken from them, and their skin becamewhite like unto the Nephites;
3 Nephi 19:30 And when Jesus had spoken these words he came again unto his disciples; and behold they did pray steadfastly, without ceasing, unto him; and he did smile upon them again; and behold they werewhite, even as Jesus.
As these passages explain, the Lamanites (forerunners of the dark-skinned Native Americans descended from the Jews according to the Book of Mormon) were given a mark of dark skin as a curse for their transgression, not toward God, by the way, but toward their brethren, the righteous Nephites. Later when some Lamanites became righteous, the curse was removed and their skin became white.
Are you saying Joseph Smith DIDN'T write the BOM? Whatever you think Coltrin had to do with LDS doctrines about the black race, you cannot ignore what is STILL in your religion's scriptures.
Here's some PROVEN history: do YOU agree with it or not?
