For the record “disputed” is not an accurate word. Rather, This idea has been blatantly shot down as false.
Well, sweet friend, I'm glad that it is no longer practiced by the majority, but it still is in some small areas in Arizona and Utah. And I did go to a Mormon president's house in the mountains of Arizona where I lived and was allowed to look up things in his set of Journal of Discourses and read the accounts for myself. They were the words of Brigham Young, himself, as I recall. He had a copier in his office and I copied the pages I found interesting. The teachings were unbelievable.
