Booker-t,
I do know that black people were not allowed into the LDS religion originally, and then they changed that somewhere along the way becasuse, if for no other reason, it made them look like racist a**holes. They also originally had a strict NO caffiene rule, but that has since changed (probably about the same time one of their uber creepy prophets bought stock in Coca-Cola), now they are allowed to drink Coke and Pepsi but not coffee. Which makes no sense to me.
A great read on the Mormon religion and their ever-changing belief system is Under the Banner of Heaven:A Story of Vilolent Faith, By John Krakauer.
It's shocking what they do "in the name of God", but as far as I'm concerned I think all organized religions suffer this sickness.
