I find it amusing that Trey Parker & Matt Stone will unabashedly mock ANYBODY right up until they receive a half-assed threat from a "muslim activist" group and all of a sudden they can't backpedal fast enough.
Chicken#$%*s.
Maybe they read the wikipedia article on Salman Rushdie?
"On 14 February 1989, a fatwā requiring Rushdie's execution was proclaimed on Radio Tehran by Ayatollah Ruhollah Khomeini, the spiritual leader of Iran at the time, calling the book "blasphemous against Islam" (chapter IV of the book depicts the character of an Imam in exile who returns to incite revolt from the people of his country with no regard for their safety). A bounty was offered for Rushdie's death, and he was thus forced to live under police protection for years afterward. On 7 March 1989, the United Kingdom and Iran broke diplomatic relations over the Rushdie controversy.
The publication of the book and the fatwā sparked violence around the world, with bookstores firebombed. Muslim communities in several nations in the West held public rallies in which copies of the book were burned. Several people associated with translating or publishing the book were attacked, seriously injured, and even killed.[23] Many more people died in riots in Third World countries.
On 24 September 1998, as a precondition to the restoration of diplomatic relations with Britain, the Iranian government, then headed by Mohammad Khatami, gave a public commitment that it would "neither support nor hinder assassination operations on Rushdie."[24][25]
Hardliners in Iran have continued to reaffirm the death sentence.[26] In early 2005, Khomeini's fatwā was reaffirmed by Iran's spiritual leader, Ayatollah Ali Khamenei, in a message to Muslim pilgrims making the annual pilgrimage to Mecca.[27] Additionally, the Revolutionary Guards have declared that the death sentence on him is still valid.[28] Iran has rejected requests to withdraw the fatwā on the basis that only the person who issued it may withdraw it,[27] and the person who issued it – Ayatollah Khomeini – has been dead since 1989.
Rushdie has reported that he still receives a "sort of Valentine's card" from Iran each year on 14 February letting him know the country has not forgotten the vow to kill him."
And some stuff I didn't know
"Failed assassination attempt and Hezbollah's comments
On 3 August 1989, while Mustafa Mahmoud Mazeh was priming a book bomb loaded with RDX explosives in a hotel in Paddington, Central London, the bomb exploded prematurely, taking out two floors of the hotel and killing Mazeh. A previously unknown Lebanese group, the Organization of the Mujahidin of Islam, said he died preparing an attack "on the apostate Rushdie". There is a shrine in Tehran's Behesht-e Zahra cemetery for Mustafa Mahmoud Mazeh that says he was "Martyred in London, 3 August 1989. The first martyr to die on a mission to kill Salman Rushdie." Mazeh's mother was invited to relocate to Iran, and the Islamic World Movement of Martyrs' Commemoration built his shrine in the cemetery that holds thousands of Iranian soldiers slain in the Iran–Iraq War.[24]
During the 2006 Jyllands-Posten Muhammad cartoons controversy, Hezbollah leader Hassan Nasrallah declared that "If there had been a Muslim to carry out Imam Khomeini's fatwā against the renegade Salman Rushdie, this rabble who insult our Prophet Mohammed in Denmark, Norway and France would not have dared to do so. I am sure there are millions of Muslims who are ready to give their lives to defend our prophet's honour and we have to be ready to do anything for that."[33] James Phillips of the Heritage Foundation testified before the United States Congress that a "March 1989" (sic) explosion in Britain was a Hezbollah attempt to assassinate Rushdie which failed when a bomb exploded prematurely, killing a Hezbollah activist in London.[34]"
