"We the undersigned petition the Prime Minister to Revoke blasphemy laws in the UK. The fact that blasphemy is still a criminal offence in Britain shows the extent of the lack of religious freedom within this country. Why should someone be punished for speaking against something they have no belief in?"This makes sense for all secularists, atheists and theists alike, as well as any non-Anglican theists whose own religion is not so protected.
Here's a description of the law:
"Blasphemy (and blasphemous libel) is a common law offence with an unlimited penalty. The content of the current law is obscure and, from the evidence that the Committee has received, is widely misunderstood.
The courts held, more generally, that it was "no longer true that 'Christianity is part of the law of the land'". The law of blasphemy was thus restricted to protecting the tenets and beliefs of the Church of England, other religions being protected only to the extent that their beliefs overlapped with those of the Church of England.
As to what precisely constitutes a blasphemy, the matter is obscure...From the decided cases it would seem that blasphemy is committed "by anyone who makes public words, pictures or conduct whereby the doctrines, beliefs, institutions, or sacred objects and rituals of the Church of England by law established are denied or scurrilously vilified or there is objectively contumelious, violent or ribald conduct or abuse directed towards the sacred subject in question, likely to shock and outrage the feelings of the general body of Church of England believers in the community". As the Law Commission's view indicates, quite what this means when it comes to applying the law to any given set of facts is difficult to say."
