Mormons are subjected to a double-whammy. At the same time that they are opposed by anti-Mormons who deem them a “non-Christian” “cult”, they are barred by anti-Christians who hate them because of their Christian religious beliefs. There exists, in effect, not one but two unconstitutional religious tests barring Romney and every other one of the millions of American Mormons from ever aspiring to the Presidency. That these two tests contradict each other in every way merely adds insult to injury.
I repeat here what I wrote there in the comments.
During the World Wars it was said that "Loose Lips Sinks Ships." Nowadays I think that idea should be revived as "Loose Terminology Sinks Ideas." The notion that since the government is not allowed to use religious tests as a prerequisite for holding political office then individual voters are not allowed to be uncomfortable with candidates who hold religious beliefs they find odd or downright weird is simple nonsense. We do not say that since the government cannot censor publications they dislike then any individual who chooses not to allow a copy of The Turner Diaries in their collection is guilty of censorship. The Constitution is a document that regulates the running of the mechanism of government, it is not a source of personal ethics. You may personally feel that voters shouldn’t ever take religious background into account, but that is nothing but the expression of your personal preference.
I myself would find it difficult to vote for a practitioner of voodoo, or a scientologist, or a believer in the divinity of Jim Jones, or someone who believes completely in astrology, therefore I cannot say that there is something inherently wrong with those people who are distrustful of Mormonism. Now, I may argue that their fears are exaggerated or completely misplaced, their ignorance too great to make any knowledgeable decision on the matter, etc., but that is an entirely different argument than the one made here.
