It’d be one thing if the state of Idaho banned all alcohol because the state sports a large Mormon population and Mormons don’t drink. That might raise a Con Law question or two, but before we could even litigate it out, the state’s many non-Mormons would rebel against the religious theocracy preventing them from drinking. (They wouldn’t call it a “theocracy” because some Grover Norquist-type would convince them that “redistributive taxes” had empowered a “Communist regime,” and the good people of Idaho would blame the black guy, but I digress.)
Banning all alcohol would be too obvious of an imposition of religious dogma upon a secular concern.
Instead, Idaho is trying to get away with a smaller encroachment of religion upon the public sphere. The state of Idaho has effectively banned the sale of one particular kind of vodka because the state believes the company’s marketing campaign is offensive to Mormons.
And no, the marketing campaign is not “drink some of this vodka and then go make fun of Mormons,” or anything the state could reasonably fear might affect the public safety of the citizens of Idaho….
