YR, I think it's just that now, the establishment has decided that questioning the value and meaning of multi-culturalism, is allowed. 20 years ago, it simply wasn't. The only ones who did it were the Daily Mail, in their usual rabid way. So JS's statements are controversial now, but not beyond the pale as they would have been then.
Re women "choosing" to wear the veil, I think as with all choices, you have to look at that in the context of the society in which they are living. I choose not to wear certain garments in certain social situations (like mini-skirts for example) because I am made to feel uncomfortable by men for wearing them; "choosing" not to wear them therefore, isn't a completely free choice, is it? Of course for many women, wearing the veil is a choice but for far too many, it's nothing like a free choice and I think it's disingenuous to pretend that it is.
Not saying you're saying that, btw, or calling JS a racist for that matter, but in RL lots of people are.
