>Walter, I think you are missing Dan's point. Would you accept sharia law even if only for muslims in Holland. In principle do you think sharia law is ok for those who wish to live under it in Holland?

I think that legal systems within legal systems aren't that uncommon. You become a member of a club, or sign a contract with some entity, and the membership rules or contract clauses pretty much become law for those who signed.

However, there's a huge difference in status - once a specific group's internal laws are recognized as laws, they become much more than club rules. If such a status change was allowed anywhere, that'd be, IMO, a mouse hole through which elephants can walk later. It's the beginning of the end of the "everyone is equal in court" axiom.
