Blasphemy is the act of insulting or showing contempt or lack of reverence to a deity, to religious or holy persons or sacred things, or toward something considered sacred or inviolable.
Some religions consider blasphemy to be a religious crime. As of 2012, anti-blasphemy laws existed in 32 countries, while 87 nations had hate speech laws that covered defamation of religion and public expression of hate against a religious group. Anti-blasphemy laws are particularly common in Muslim-majority nations, such as those in the Middle East and North Africa, although they are also present in some Asian and European countries.
The word "blasphemy" came via Middle English blasfemen and Old French blasfemer and Late Latin blasphemare from Greek βλασφημέω, from βλάπτω "injure" and φήμη "utterance, talk, speech". From blasphemare also came Old French blasmer, from which English "blame" came. Blasphemy: 'from Gk. blasphemia "a speaking ill, impious speech, slander," from blasphemein "to speak evil of."' "In the sense of speaking evil of God this word is found in Ps. 74:18; Isa. 52:5; Rom. 2:24; Rev. 13:1, 6; 16:9, 11, 21. It denotes also any kind of calumny, or evil-speaking, or abuse (1 Kings 21:10 LXX; Acts 13:45; 18:6, etc.)."
In some countries with a state religion, blasphemy is outlawed under the criminal code. Such laws have led to the persecution, lynchings, murder or arrest of minorities and dissident members, after flimsy accusations.
As of 2012, 33 countries had some form of anti-blasphemy laws in their legal code. Of these, 21 were Muslim-majority nations – Afghanistan, Algeria, Bahrain, Egypt, Indonesia, Iran, Jordan, Kuwait, Lebanon, Malaysia, the Maldives, Morocco, Oman, Pakistan, Qatar, Saudi Arabia, Somalia, Sudan, Turkey, the UAE and the Western Sahara. The other twelve nations with anti-blasphemy laws in 2012 were Denmark (abolished in 2017), Finland, Germany, Greece, India, Ireland, Italy, Malta (abolished in 2016), the Netherlands (abolished in 2014), Nigeria, Poland and Singapore. Blasphemy was treated as a capital crime (death penalty) in many Muslim nations.
