If you're one of these people who's OD'd on the Horowitz crowd and you lie awake sweating over the impending fall of Western civilization, this is the book for you. There aren't enough Muslims in the US to be statistically significant and probably never will be, and England won't magically turn into Iran any time soon. And yeah, Melanie Phillips really has shown herself to be a a bit of a twit and a whiner, hasn't she?
The problem here is about what one would expect. Much like Noam Chomsky or Ian Buruma, though in an admittedly far less toxic way, because he's clearly non-PC, Doug Saunders doesn't have a very firm grasp of what Islam actually is, and what it has really done to impede any social OR ETHICAL progress in Dar-al-Islam, and why.
He has a long section comparing the position of Muslim immigrants with that of previous Catholic and Jewish ones. It's a really shallow analogy, because Islam is a radically different KIND of religion than either. As follows:
"I am in agreement with secular Muslims like Salman Rushdie and Ayaan Hirsi Ali ... when they argue that the instructions of the Koran ... are enormously harmful to those who are subject to them, especially women ... (p. 6)."
Catch what's wrong here? Rushdie and Ali are not Muslims at all!!! They're apostates, and hence under death sentences. Further, they know a LOT more about the Koran than Saunders does. Example: Muslims are ordered not to fraternize with, or sympathize with, the infidels for fear of risking damnation, and these orders are absolute and forever. No wonder so many have a difficult time integrating. Further, if it will take one Muslim family two or three generations to integrate fully, what about the fact that fresh immigrants will have to repeat the process indefinitely?
I can recommend this book, but with a STRONG proviso. Before you buy it, watch a couple of Youtube videos. One, by Taslima Nasrin, entitled "My Fight for Secularism," will give you some idea of what intelligent Muslims have to put up with. It will literally bring tears to your eyes. The other, by Maryam Namazie, is entitled "Islamic Inquisition." And be sure to catch the question and answer bit at the end, where she DESTROYS a moderate Muslim, of the sort Doug Saunders wants to cultivate here in the West.
In Namazie's view, as in the views of so many ex-Muslim intellectuals who have to live with constant threats of violence, there really is no distinction between Islam (i.e. the "religious" kind) and Islamism (the radical "political" kind). Since Islam was political BEFORE it was religious (see Tom Holland's recent history thereof on this point) they are precisely the same thing, and this has never been true of Christianity, which is why Islam has so often been at war with Christianity.
The refusal of both "moderates" and Western "liberals" to recognize this is nearly as morally cancerous as the death-penalty-for-apostasy tradition it sugar-coats, because it allows the latter.
I'm afraid that Saunders' solution, "Hey, folks, let's just chill," won't solve the problem, only prolong it, because the "problem" of Muslim immigration is really one of two inimical systems of ethics. And one of them is a dark age fossil.
