The law is the law is the law, and Sharia law ought not, and we need not fear that it ever might, intrude on the proper domain of civil law.

OK, that’s this man’s view. Now, for another view, we have Theodore Dalrymple.

Source article, highly recommended.

…[snip, we come into the article mid-stream] Juliet’s plea to her mother to abrogate an unwanted marriage to Paris, arranged and forced on her by her father, Capulet—would so uncannily capture the predicament of some of my Muslim patients in Britain more than a third of a century after my visit to Afghanistan, and four centuries after they were written:

Is there no pity sitting in the clouds
That sees into the bottom of my grief?
O sweet my mother, cast me not away!
Delay this marriage for a month, a week,
Or if you do not, make the bridal bed
In that dim monument where Tybalt lies.

How often have I been consulted by young Muslim women patients, driven to despair by enforced marriages to close relatives (usually first cousins) back “home” in India and Pakistan, who have made such an unavailing appeal to their mothers, followed by an attempt at suicide!

Capulet’s attitude to his refractory daughter is precisely that of my Muslim patients’ fathers:

Look to’t, think on’t, I do not use to jest.
Thursday is near, lay hand on heart, advise:
And you be mine, I’ll give you to my friend;
And you be not, hang, beg, starve, die in the streets,
For by my soul, I’ll ne’er acknowledge thee,
Nor what is mine shall ever do thee good.

In fact the situation of Muslim girls in my city is even worse than Juliet’s. Every Muslim girl in my city has heard of the killing of such as she back in Pakistan, on refusal to marry her first cousin, betrothed to her by her father, all unknown to her, in the earliest years of her childhood. The girl is killed because she has impugned family honor by breaking her father’s word, and any halfhearted official inquiry into the death by the Pakistani authorities is easily and cheaply bought off. And even if she is not killed, she is expelled from the household—O sweet my mother, cast me not away!—and regarded by her “community” as virtually a prostitute, fair game for any man who wants her.

This pattern of betrothal causes suffering as intense as any I know of. It has terrible consequences. One father prevented his daughter, highly intelligent and ambitious to be a journalist, from attending school, precisely to ensure her lack of Westernization and economic independence. He then took her, aged 16, to Pakistan for the traditional forced marriage (silence, or a lack of open objection, amounts to consent in these circumstances, according to Islamic law) to a first cousin whom she disliked from the first and who forced his attentions on her. Granted a visa to come to Britain, as if the marriage were a bona fide one—the British authorities having turned a cowardly blind eye to the real nature of such marriages in order to avoid the charge of racial discrimination—he was violent toward her.

Emphasis mine. The point is, it is not in fact true that aspects of Sharia law never, or effectively never, penetrate into the real-world workings of western courts.

Bold-facing mine.
