Sharia and claims of conscience

Yesterday I wondered whether we were going to start seeing the "Sharia" label attached to any request by a religious believer for conscience-based exemptions from generally applicable laws.  Apparently that train has already left the station.  Consider this statement:

"Religious rules should end ‘at the door of the temple’ and give way to the ‘public law’ laid down by Parliament.”

“To me, there’s nothing different in principle with a Catholic adoption agency, or indeed Methodist adoption agency, saying the rules in our community are different and therefore the law shouldn’t apply to us. Why not then say sharia can be applied to different parts of the country? It doesn’t work,” he added.

And who's the "he?"  Must be some guy sitting in his basement writing a blog post for an audience of three, right?.  He couldn't be the chairman of the British Equality and Human Rights Commission, could he?
