One time I heard a Brigham Young quote where he was saying that every single young man over the age of twenty five should see Menace II Society.
That's why I can't understand anyone doubting that Brother Brigham was a prophet. That movie came out 116 years after he died and not only did he know its gritty portrayal of urban life would be very influential on our modern Mormon culture, but he also knew it would not be appropriate for children to watch.
And he was right.
He was always right.
