Blasphemy law is a law limiting the freedom of
speech and expression relating to blasphemy, or irreverence toward
holy personages, religious artifacts, customs, or beliefs.
In place of, or in addition to, prohibitions against
blasphemy, some countries have laws which give redress to those who
feel insulted on account of their religion. These laws forbid hate
speech, the vilification of religion.
In most countries, blasphemy is not a crime. In the
United States of America, for example, a prosecution for blasphemy
would violate the Constitution according to the decision in Joseph
Burstyn, Inc v. Wilson. The United Kingdom abolished its laws against
blasphemy in England and Wales in 2008. The last person hanged for
blasphemy in Great Britain was Thomas Aikenhead aged 20, in Scotland
in 1697. He was prosecuted for denying the veracity of the Old
Testament and the legitimacy of Christ's miracles.
Similarly, in practically all of the developed
Western world and East Asian developed democracies like Japan and
Taiwan, blasphemy laws, when existent, are largely de facto dead
letter.
