In any case, I did not say caffeine was prohibited. I said Mormons are "not supposed" to drink caffeine. In the English language most people recognize that there is a difference between the words "should" and "must".
As it is laid out in the handbook on their website:
"Members should not use any substance that contains illegal drugs. Nor should members use harmful or habit-forming substances except under the care of a competent physician."

Caffeine, though not addictive, is habit-forming.
So is Orange Juice, sunflower seeds, butter on mashed potatos and Hot Cocoa before bedtime. When you attack a group of people based on their religion, it's generally considered 'offensive'. I'm LDS, and I tire of the continual attacks by people who know little, if anything about the LDS faith.
If you want a list of things we aren't 'supposed' to touch, it's in the Word of Wisdom. This includes tobacco, coffee, strong alcohol. Why? Will we go to hell if we do these things? Nope, absolutely not. But, they have more negatives than positives attached to them. Some people can drink a glass a wine every day - in fact, we recognize this as a beneficial thing to do. However, how many millions of lives and family have been runed by alcoholism? Does the bad outweight the good? It's simply advice we are encouraged to follow - to avoid placing ourselves, and our families at risk. Seriously, is this bad advice?
So, when you attack "Mormons" - you might as well scream "Nigger" and be amazed that someone will call you on it. You won't see me attacking Catholics, Baptists, Lutherns or any other Christian denomination (this does NOT apply to Islam) - it's because I RESPECT other people; all I ask is that some respect be shown in return.
