Nothing will happen until Britain (and the U.S.) declares that Islam is a two-headed entity. One head is a religion and will be treated as such insofar as it acts in the realm of traditional religion. The other head has no role in the religious realm but is an earthly civic institution with its own set of rules and goals (sharia, jihad, etc.)that is inconsistent with Western culture and laws that will be prosecuted fully when they conflict therewith.
One cannot separate Jihad and Mad Mo’ from Islam.
