… has a compelling op-ed on OpinionJournal.com. Here’s part, but it’s all well worth reading:

The majority of European Muslims do not approve of terrorism. But there are majorities and majorities. According to a recent poll, a full quarter of British Muslims believe that the bombs of last summer in London were a legitimate response to the “war on terror.” Public pronouncements from Muslim leaders treat Islamist terrorism as a lamentable but understandable response to the West’s misguided policies. And the blood-curdling utterances of the Wahhabite clergy, when occasionally reported in the press, sit uneasily with the idea of a “religion of peace.” All this leads to a certain skepticism among ordinary people, whose “racist” or “xenophobic” prejudices are denounced by the media as the real cause of Muslim disaffection.
Now of course it is wrong to give gratuitous offence to people of other faiths; it is right to respect people’s beliefs, when these beliefs pose no threat to civil order; and we should extend toward resident Muslims all the toleration and neighborly goodwill that we hope to receive from them. But recent events have caused people to wonder exactly where Muslims stand in such matters. Although Islam is derived from the same root as salaam, it does not mean peace but submission. And although the Koran tells us that there shall be no compulsion in matters of religion, it does not overflow with kindness toward those who refuse to submit to God’s will. The best they can hope for is to be protected by a treaty (dhimmah), and the privileges of the dhimmi are purchased by onerous taxation and humiliating rites of subservience. As for apostates, it remains as dangerous today as it was in the time of the prophet publicly to renounce the Muslim faith. Even if you cannot be compelled to adopt the faith, you can certainly be compelled to retain it. And the anger with which public Muslims greet any attempt to challenge, to ridicule or to marginalize their faith is every bit as ferocious as that which animated the murderer of Theo Van Gogh. Ordinary Christians, who suffer a daily diet of ridicule and skepticism, cannot help feeling that Muslims protest too much, and that the wounds, which they ostentatiously display to the world, are largely self-inflicted.
To recognize such facts is not to give up hope for a tolerant Islam. But there is a matter that needs to be clarified. Christians and Jews are heirs to a long tradition of secular government, which began under the Roman Empire and was renewed at the Enlightenment: Human societies should be governed by human laws, and these laws must take precedence over religious edicts. The primary duty of citizens is to obey the state; what they do with their souls is a matter between themselves and God, and all religions must bow down to the sovereign authority if they are to exist within its jurisdiction.
The Ottoman Empire evolved systems of law which to some extent replicated that wise provision. But after the Ottoman collapse the Muslim sects rebelled against the idea, since it contradicts the claims of the Shariah to be the final legal authority. The Egyptian writer and leader of the Muslim Brotherhood, Sayyid Qutb, went so far as to denounce all secular law as blasphemy. Mortals who make laws for their own government, he argued, usurp a power which is God’s alone. And although few Muslim leaders will publicly endorse Qutb’s argument, few will publicly condemn it either. What to us is a proof of Qutb’s fanaticism and egomania is, for many Muslims, a proof of his piety.
