All of which gets us back to Keith Ellison and his originally stated intention to take the oath of office relying solely on his Koran. Although there is often a vast chasm between theory and practice, theory, as I understand it, says that a true Muslim cannot simultaneously believe in the Koran's dictates and swear an oath to protect a Western legal document such as the Constitution. The two documents (the Koran and the Constitution) envision entirely antithetical laws and the Koran mandates that its believers, as part of their faith, bend every effort to ensuring the Koran's ascendancy over all other forms of government and faith.

In other words, Prager was wrong about Ellison's using the Koran at his swearing-in, not because it represented an act of multiculturalist self-obsession, but because a really religious man cannot do both acts at the same time. That is, as a devout Muslim, one cannot swear to support any political system other than Shari'a, and one certainly can't do so using the very same Koran that proscribes all other systems.

[Bukhari:V7B67N427] "The Prophet said, ‘If I take an oath and later find something else better than that, then I do what is better and expiate my oath.'"
