Good luck abrogating the Koran. I do wish you God's speed on your quest to understand Islam, because clearly you don't.
" it is essential for us to work with Muslims that both respect the constitution AND still hold fundamentally Islamic beliefs."
Muslims can only do one or the other. If they respect "mans laws" then they die hypocrates and burn in hellfire according to their cult.
The Koran cannot be abrogated- that carries a death penalty, just as throwing a gum wrapper on the mosk lawn does, and just as being an apostate (leaving the religion) does. You are either a Muslim, or you are not. DO you know what a "moderate Muslim" really is? It's a uneducated muslim that has never read the koran. There are a lot of them, it's true. That's because Muslims recieve Islam orally, by equally ignorant Imams, in impoverished lands where education is learning to recite the koran by memory in a language they don't even speak (arabic)
The sad thing is, even if these ignorant muslims are shown what the Koran really says, they still choose Islam. The "moderates" become fundamentalists, not extremists. There is no such thing as an extremist muslim, just one who correctly follows and implements its teachings.
