But you don’t bring “peace,” Skippy, by establishing an Iraqi Constitution that establishes “Islam” as the source of all legislation. Islam is the problem, not the solution.
At least that's the charge the Sunni make, and there's a lot of validity to it.
In some parts of the world, and Iraq is in such a "part", people find it inconceivable that there should not be a state church, or that religion should be anything other than the guiding principle of society.
In America we generally believe a state religion is total nonsense and probably dangerous to your health. We also believe in free speech. We are in a tiny minority in this world.
