"Article 2
Islam is the official religion of the State and it is a fundamental source of legislation . . . No law that contradicts the established provisions of Islam may be established.
Any idea where that statement comes from? "
You conviently ommitted the rest of article 2:
{B. No law that contradicts the principles of democracy may be established.
C. No law that contradicts the rights and basic freedoms stipulated in this constitution may be established.
Second: This Constitution guarantees the Islamic identity of the majority of the Iraqi people and guarantees the full religious rights of all individuals to freedom of religious belief and practice such as Christians, Yazedis, and Mandi Sabeans.}
Your half-truths would be better suited at the DU and the MSM.
If and when this demand comes into conflict with other articles in the Constitution, such as those referring to democracy and the rights of other religions, it's clear to me at least which of these articles will prevail and which will be subordinated.
As for the "full religious rights" of Christians, as of now, they're non-existent.
