The letter Adapt religion to suit modern times is interesting and good material for debate as to whether Islam as a universal religion is practical when it comes to application of the Islamic state.

What exactly is the nature of an Islamic state and what are principles it upholds if there is such a state? All this need to be expounded upon and analysed in detail before any conclusions are made.

It is not proper for someone to make generalised statements regarding the relevancy of an Islamic state without detailed analysis of the matter.
