In democracyarsenal.org, Shadi Hamid makes a Note to Muslims objecting to a the claim by Zaid Shakir that his wish for an Islamic law is shared by “every Muslim who is honest”.
Perhaps the wish for a Muslim country governed by Islamic law is parallel to the wish for a Christian nation governed according to Christian principles, or perhaps it is for sharia law which might be more parallel to asking to be governed by strictly literal Biblical rules. None of the four appeals to me but all are advocated by at least some of the religious “leaders” of each faith.
The claim that “every honest” Whateverist wants a Whateverist government may be denied by what Basil refers to as “Eid-Muslims” and “Christmas-Christians”, but to those who believe that their faith clearly demands committment to its establishment in law, those who do not make that demand are legitimately cast as dishonest.
In the case of Christianity, disestablismentarianism is so evident in scriptural teaching that to any reasonable person (ie anyone who agrees with me) it is clear that it is actually those who would establish religious law who are making a dishonest interpretation. Unfortunately, for Islam, so far as I understand it, this is not the case.
