Almost all Islamic countries are not open societies. If anyone in those countries say anything which is against their religion then either he will be punished under blasphemy law (if that country has blasphemy law) or he would be attacked, killed or threatened by religious extremists and that person would either have to leave that country or live in fear. An example of such and incident was when a 19 year old Muslim girl was stoned to death after taking part in beauty contest in Ukraine.
There is blasphemy law in Pakistan which prohibits blasphemy against Islam. Anyone knowingly or unknowingly doing or saying anything which is against Islam would be prosecuted. The punishment ranges from a fine to death.
In November 2010, Asia Bibi was sentenced to death by hanging on a charge of blasphemy.
Pakistani Punjab Governor Salman Taseer opposed blasphemy law he supported Asia Bibi. He was against blasphemy law which the Muslims didn't like. In 2011 Salman Taseer was shot dead by his security guard named Mumtaz Qadri for supporting Asia Bibi and opposing blasphemy law. But what's worse was that Mumtaz Qadri the murderer was supported by the Muslim people. Thousands of people gathered and showered flowers at him. People applauded killing of Salman Taseer which was a case of sick religious fanaticism and murder of open society.
