We Don't Know Why

Why Noah cursed Canaan and his descendants is not made clear in the Bible. LDS General Authorities have provided no guidance as well. So we Latter-day Saints are left without an explanation as to why this restriction was put in place in the first place. There has been a lot of speculation by members and nonmembers alike as to the cause. But as far as I know, the Lord has never spoken of His reasons for the restriction. I certainly am not willing to speculate.
