all i would need to see would be for him to clearly state that his oath of office would come ahead of any church directions to him, like JFK did. He steadfastly refuses to discuss it, thus leaving the door open to his White Horse Prophesy, and viewing a mormon president as the leader of his church, too. And his church's teachings don't exactly line up with a majority of america's.
It would be sort of similar to our genocide of the Indians who were settled here ...wouldn't it? Except we really didn't suffer the persecution from the Indians as the Mormons suffered from many places here .. .
