"Our Constitution disallows any religious tests for office."
Obviously you are a twit. The Constitution certainly places no limit on what religions can run for public office. Neither does it compel anyone to vote for satanists, scientologists, wiccans, santerists, or even mormons in disregard of their religious views. Puhlease, why don't you quote the exact line of the Constitution that says all religious tests are disallowed WHEN VOTING FOR A CANDIDATE. Since you cannot find such an article why don't you buy a clue and actually read the Constitution instead of pulling things out of your ear.
And while you might 'expect' candidates to be governed by the Constitution despite religious predilections, Mormons believe they are on the path to becoming Gods themselves. At what point do you think someone who thinks they are becoming a God might just decide they are more wise and powerful than something called the Constitution? I've seen it in Mormons before (one example being Harry Reid).
So, in short, don't come to a mental shootout carrying a peashooter.
Excellent...but it's more like a slingshot.
"Obviously you are a twit."
You must be leading with the argument which defines your approach to discussion.
