I'll take care of my own religious freedom, thanks anyway.

Australia's Victoria Province tried a religious tolerance law much like the one Britain is trying to pass. Not a fantastic success:

Small teams of Christians, armed with notepads and tape recorders, began attending Islamic lectures, recording possible transgressions that might be used as evidence in the case. Islamic bookstores were mined for nuggets of intolerance. True to its promise, the law had brought Christians and Muslims together like never before.

The court case dragged on for months as the judge listened to complex theological evidence tendered by both sides. Arguments flew back and forth about the nuances of Arabic grammar, the interpretation of various verses of the Koran, the requisite qualifications for Islamic scholarship, and the relative legitimacy of different schools of Islamic jurisprudence. Nobody, it seemed, noticed the inappropriateness of a secular court, more accustomed to matters of trade practices disputes and parking fines, presiding over a case centering on contentious theological arguments. [Emphasis Added]

Yeah, that's not good.
