Black Mormons...

The Church of Jesus Christ of Latter Day Saints has a mixed history when it comes to members of African descent. On the one hand, the LDS Church denied black people the priesthood, and admission to temple rites, until the 1970s, claiming their dark skin was the "mark of Ham." On the other hand, the early Mormon community included free blacks and their attitude toward slavery may have contributed to the troubles they had with their neighbors in Missouri back in 1838.

Today the LDS has a reputation for whiteness.
