The fact is, it has been open season on Christianity for sometime in Britain.
The impetus behind this law is not to shield Christians from abuse but to prevent any criticism of Islam and, more importantly, to allow Muslims to use the courts to fight Christians who are peacefully witnessing Christ to Muslims.
As a Christian I would prefer to allow others to mock my beliefs and still be allowed to talk to Muslims about Christ than to ensure that I not be offended at the cost of being legally restrained from preaching the Gospel.
