No, he didn't actually mention Serrano or his notorious P*** Christ, but when he says that someone who harms "the prophets of other monotheistic religions" ought to be beheaded along with the Motoon cartoonists, shouldn't Serrano look into hiring bodyguards?

A We're-All-In-This-Together Alert from the most influential center of Sunni Islam: "Al-Azhar Sheikh: A Muslim Who Harms Books Holy To Non-Muslims Must Be Beheaded," from [1] MEMRI (thanks to Sr. Soph):

In response to the Muhammad cartoons published by Danish papers and to the recently released film by Dutch MP Geert Wilders, Al-Azhar Sheikh Muhammad Sayyed Tantawi said: "Any reasonable person must speak out vehemently against harming the Koran and insulting the Prophet, and must use an iron hand against those who do so."

He said that if a Muslim harmed books holy to non-Muslims, or harmed the prophets of other monotheistic religions, "we would demand that he be punished as a lesson to all, and that he must be beheaded."
