The Oath on the Bible of the US-President is the key of the Massacre of Newtown and future Massacres. The iniquity of the nazi System was not so great. Because Adolf Hitler does make the choice of paganism, as Friedrich Nietzsche does, or Lady Gaga (and all those pop-singers who do repeat constantly this basic knowledge that Satan is the master of the human Carnival.)
Though US-President does make the choice of Paganism, as the Roman Bishop, 'in the name of the Bible'. What would you think about a friend of you who would swear on a book that he obviously never read? Either that he is mad, or that he is laughing at you.
