Yes, we are speaking at cross purposes, Zac's Master.
In a true Islamic state there is no man-made law, only God's law, - the Sharia. Under sharia "modest" dress is obligatory for all Muslims (both men and women) . There is no separation in Islam between the religious and the secular. The concept "Render under to Caesar the things that are Caesar's and to God the things that are God's" is a Christian distinction and has no equivalence in Islam. That is why there is always social strife in Muslim-majority countries which have secular rule and constitutions, and why any sizeable Muslim minority in mainly non-Muslim nations punch well above their weight in general mischief-making (i.e. demanding concessions by the host society to Muslim sensibilities). Western societies and secular Muslim leaders like Mubarak and Assad don't have legitimacy in the eyes of the pious (that is groups like the Muslim Brotherhood in Egypt etc. and their proxies and affiliates throughout the West). I think the way it is usually expressed is that a legitimate government must enforce what Allah decrees and ban what Allah forbids.
