Farewell, Then, To The Blasphemy Law

Although I'm not convinced (to put it at its mildest) that widespread disregard is a good enough reason to abolish a criminal offence. Where would it end? I have a feeling that we are about to find out with regard to drugs, post-pubescent underage sex, and much else besides: "Well, we repealed the blasphemy law because so many people were just ignoring it, so why not repeal this for the same reason?"
