I understand (in some small way) comments that support implimentation of such an idea - "The Jews are allowed to practice their religious laws, so are the Hindu's and Sikh's, so why not the Muslems?" - no link I'm afraid, I heard it last night on the radio.

However, I'm fairly sure that these others have little or no conflict when it comes to their religious laws being superseded by British Law. I don't see Shariah being quite so compliant somehow.
I think it's fair to allow Islamic law regarding marriage/divorce and similar civil disputes to have its place alongside UK civil law. As said, others do it, and so do the Islamic community here today.
In reality, what is being asked for is to have Shariah develop above the influence of UK law. Perhaps if certain elements from the Islamic community here in the UK were a little less fanatical and some aspects of the proposed Islamic law were a little more progressive in their thinking, the backlash against such a request might be less absolute.

I still think that it's the proverbial 'thin end of the wedge' for those who would be prepared to exploit it.
