religion has no place whatsoever in government. It does not matter what religion it is. Islam, Christianity, Pastafarianism... None of it.
What if the popular view of the people is that religion ought to be the government, as has been the case in most of the middle east for most of history?
Religion and government aren't incompatible, religion and democracy are. Governments serve the people, and most of the people in the middle east follow Sharia law anyway, so there's no reason for Sharia law not to be set in stone legislatively. They have no interest in having anybody around that doesn't follow their customs, so they're protecting their way of life through the political process.
Just putting another opinion out there (hopefully you won't notice the huge hole in what I said)
