I think the three of us know exactly WHY the Mormon Church is placing this restriction.
How about tatoos. Mormonism prohibits tatoos. Should we extend the prohibition against tatoos, or multiple piercings?
It isn’t like coffee, tea or cola are abhorrent substances that would actually defile the BUILDING in any way. Mormons allow food and drink into the building during many social functions. The only time of defilement is to Mormons who partake of the substances. The substances themselves are not “evil.” This is nothing like a ham sandwich.
You should run for office and then get a law enacted requiring that no Churches whatsoever be used as polling places.
