just trying to figure out exactly what's sticking.... gagging... in your thinking about religion. This seems to be a reference to the Word of Wisdom in LDS doctrine/cultural construct. Pretty sure every little cult or major religion has some items that are "convenient classifiers" that can immediately be applied on the scantest evidence by the weakest of minds among the set.
If you like to drink, smoke, use tea or coffee, or perhaps even do so immoderately, or with deplorable excess, the analysis would not measure up to the more educated Mormons, imo. Within four or five decades, we had some general authorities who would tell bishops that if the couldn't smell the tobacco in their congregation, they weren't doing their job. The intended point in that was that folks needed to be more welcoming to their non-member neighbors and straying family members, a sort of "this is a hospital for sinners, not a museum for Saints" idea.
And within a hundred years, we had general authorities who used graphic (expletive-laced) language and used tea, coffee, alcohol and tobacco. It was understood to be mere "advice" until the Prohibition Era (circa 1920-30), and was not especially correlated with the fundamental virtues or measurements of the faith.
My father, as a young man going to college, wrote a brilliant scientific defense of the Word of Wisdom circa 1932, but by 1943 while teaching flying school for the air force began using coffee every morning. By 1950, when accepting an award as the "Best Teacher" award in an assembly, in a Mormon-run school, held the challis up high and turned it upside down, observing "What??? No Beer????", creating a raucous roar in the Mormon studentbody.
I attribute the downward intellect appearing presently to "common-core" type of educational theory, which has long prevailed in the LDS Sunday School. yah know.... compliance-centered rote.
