Really?
Well if it does happen (heaven help us if it does), guess who will lose out because it certainly won't be the men.
There are over 50 muslim countries in the world so if someone wants to observe sharia law, I'm sure one of them will accommodate their lifestyle choice.
My parents came from Jamaica in the 1960s and even though they retained their culture, they observed British law.
My personal opinion is that Sharia law is incompatible in a country where laws are in place to protect and uphold the rights of women because it is usually women who receive a raw deal.
There was a documentary shown a few years ago which followed a female lawyer in an African country (cannot remember which one - might have been Nigeria) who adjudicated over cases where women seeked redress in civil courts whilst their husbands went to the Sharia courts. It made me thankful to live in this country.
Also remember the case of the Muslim woman in Nigeria who was sentenced to death for having an affair with a married man which resulted in a child? He was given a slap on the wrist and told not to do it again.
